Greptile SummaryThis PR expands the Resend integration with contact operations, batch and scheduled-email support, additional webhook events, updated provider schemas, and Svix-compatible webhook verification.
Confidence Score: 3/5The PR should not merge until the cancellation test uses the configured sender and the contact contract tests can no longer pass without invoking their endpoints. The cancellation setup can fail before reaching the endpoint because it sends from an unverified hardcoded address, while the previously reported contact tests still return successfully when their prerequisite contact is missing.

The new emails.batch, emails.cancel, and five contact operations have no corresponding endpoint tests, leaving their provider paths, methods, request bodies, response schemas, and persistence behavior outside the required test coverage.

- Around line 34-39: Update the create and update event logging around
logEventFromContext so it never persists the full contact input; log only
non-sensitive contact identifiers and apply the required retention policy before
recording each event.
In `@packages/resend/endpoints/types.ts`:
- Around line 220-238: Update ContactsCreateResponseSchema and
ContactsUpdateResponseSchema to validate only the returned object and id fields,
then fetch the complete contact before parsing or upserting it as ResendContact.
Keep ContactSchema for get and list responses where full contact fields are
returned.
In `@packages/resend/index.ts`:
- Around line 321-325: Rename the webhook schema key in the contact event
binding from contacts.update to contacts.updated so it matches the existing
nested webhook binding and enables schema lookup and payload validation for the
public contact-updated path. Keep the description, payload schema, and response
schema unchanged.
In `@packages/resend/webhooks/contacts.ts`:
- Around line 35-50: Prevent out-of-order Resend lifecycle events from
recreating deleted records by adding persistent event-watermark or
deletion-tombstone checks. Update the contact create upsert near
packages/resend/webhooks/contacts.ts lines 35-50 and contact update upsert at
lines 97-112 to reject stale events; retain deletion ordering state at
contacts.ts lines 157-163 and domains.ts lines 159-165 for the existing domain
create/update handlers.
- Around line 28-31: Remove the email field from the contact event logs in
packages/resend/webhooks/contacts.ts at lines 28-31, 90-93, and 152-155; retain
only the event type and approved correlation value in the created, updated, and
deleted contact handlers.
In `@packages/resend/webhooks/emails.ts`:
- Around line 381-390: Replace verifyResendWebhookSignature with Svix-compatible
verification using svix-id, svix-timestamp, and svix-signature, the
Base64-decoded whsec_ secret, timestamp validation, and the v1 signature over

new verifier, and update its tests accordingly.
In `@packages/resend/webhooks/types.ts`:
- Around line 180-187: Update the suppression event schema object to replace
reason with a nested data.suppressed model containing message and type, then
update the webhook handler to read and log those suppression details through
data.suppressed. Preserve the existing field types and optionality where
applicable.
- Around line 202-204: Update DomainStatusSchema to include the
partially_verified and partially_failed status values alongside the existing
verified, pending, and failed values, so DomainUpdatedEventSchema accepts
payloads using either status.
- Around line 251-293: Update ContactCreatedEventSchema,
ContactUpdatedEventSchema, and ContactDeletedEventSchema to define the contact
identity as data.id instead of data.contact_id, then update all corresponding
contact event handlers to read event.data.id for persistence and deletion.
Remove reliance on the obsolete contact_id field while preserving the existing
event behavior.
- Around line 235-245: Update DomainDeletedEventSchema and the DomainDeleted
event handler in domains.ts to use event.data.id as the deleted-domain identity
instead of data.domain_id, ensuring deleteByEntityId receives that id and
removes the local domain record.

Resend webhook verify signature svix-id svix-timestamp signed payload whsec documentation
💡 Result:
To verify a webhook signature from Svix, you must use the raw (unparsed) request body along with the provided headers to ensure the cryptographic signature remains valid [1][2][3]. The verification process involves three primary headers: - svix-id: The unique identifier for the webhook message [2][3]. - svix-timestamp: The timestamp of the attempt in seconds since the epoch [2][3]. - svix-signature: The Base64 encoded list of signatures (often space-delimited) [2][3]. Note: Some customers may have these headers white-labeled as webhook-id, webhook-timestamp, and webhook-signature [3]. Manual Verification Steps: 1. Construct the signed content by concatenating the ID, timestamp, and the raw payload body, separated by a full-stop character: signed_content = ${svix-id}.${svix-timestamp}.${raw_payload} [2][3]. 2. Determine the expected signature by performing an HMAC with SHA-256 on the signed_content [2][3]. 3. Use the base64-encoded portion of your signing secret (the part after the whsec_ prefix) as the HMAC key [2][3]. 4. Compare the generated signature against the values provided in the svix-signature header. Be sure to remove the version prefix (e.g., v1,) before comparing [2][3]. It is highly recommended to use the official Svix libraries, which handle these steps automatically, including timestamp verification to prevent replay attacks [1][2][4]. When implementing, ensure your server does not parse the request body (e.g., using express.json) before passing it to the verification function, as any modification will break the signature [1][5][6].

Replace the verifier with Svix-compatible verification.
The shared verifier uses HMAC-SHA256(rawBody, webhookSecret) with a sha256= prefix. Resend uses svix-id, svix-timestamp, and svix-signature; it signs svix-id + "." + svix-timestamp + "." + rawBody with the Base64-decoded whsec_ secret. Require all three headers, validate the timestamp, and check the v1 signature. Update the verifier tests and all listed handlers.

Resend webhook email.suppressed payload data suppressed message type
💡 Result:
The email.suppressed webhook event is triggered when an email is blocked from being sent because the recipient address is already on a suppression list [1][2]. This event indicates that no delivery attempt was made to the recipient's mail server for that specific email [3][4]. For the Resend platform, the payload for the email.suppressed event includes the following core structure: Type: The event type is consistently identified as email.suppressed [1]. Data Object: The data field contains details about the blocked email, including [1]: - identifiers such as email_id, broadcast_id, and message_id (the RFC Message-ID header value) [1]. - metadata about the sender, the recipient (as an array), and the subject [1]. - a suppressed object that specifies the reason for the suppression and the type of suppression (e.g., OnAccountSuppressionList) [1]. - relevant template IDs and tags associated with the email [1]. While other email service providers may use similar event names (e.g., email.suppressed) [5][6], the exact payload structure can vary between platforms [3][5]. If you are working with Resend, you should refer to their official documentation for the exact field names and nesting structure [1][2]. Regardless of the provider, it is recommended to implement idempotency using the provided identifiers to avoid duplicate processing of these events [3].

Resend webhooks contacts contact.created contact.updated contact.deleted payload data.id official documentation
💡 Result:
Resend supports three webhook event types specifically related to contacts: contact.created, contact.updated, and contact.deleted [1][2]. These events are triggered when a contact is successfully created, updated, or deleted, respectively [1][3][4][5]. Webhook Payloads All Resend webhook payloads follow a consistent structure [4][5][6]. The payload is a JSON object containing the event type, a timestamp (created_at), and a data object that houses the specific contact information [3][4][5]. Within the payload, the data.id field represents the unique identifier for the contact [4][5]. Example Payload Structure The following JSON structure is consistent across the contact.created, contact.updated, and contact.deleted events [3][4][5]: { "type": "contact.created", // or "contact.updated" / "contact.deleted" "created_at": "2026-11-17T19:32:22.980Z", "data": { "id": "e169aa45-1ecf-4183-9955-b1499d5701d3", "audience_id": "78261eea-8f8b-4381-83c6-79fa7120f1cf", "segment_ids": ["78261eea-8f8b-4381-83c6-79fa7120f1cf"], "created_at": "2026-11-17T19:32:22.980Z", "updated_at": "2026-11-17T19:32:22.980Z", "email": "steve.wozniak@gmail.com", "first_name": "Steve", "last_name": "Wozniak", "unsubscribed": false } } Important Note: These contact-related webhook events are not triggered when importing multiple contacts via CSV [1][3].

Use data.id as the contact identity in all contact events.
Resend sends the contact ID in data.id, not data.contact_id. The schemas reject these payloads, and the handlers skip persistence or deletion because they check event.data.contact_id. Update the schemas and handlers to use id.

In `@packages/resend/api.test.ts`:
- Around line 110-130: The emailsCancel test must create a future scheduled
email, capture its returned ID, and cancel it through POST
emails/{emailId}/cancel instead of selecting a listed email and issuing DELETE
emails/{emailId}. Update the emailsCancel implementation and the test request
method/path accordingly, preserving validation with
ResendEndpointOutputSchemas.emailsCancel.
- Around line 260-271: Update the Resend lifecycle tests to preserve the created
contact ID from contactsCreate, assert the returned ID rather than
testContactEmail, and move contact cleanup into afterAll. Make the get, update,
and delete tests fail when the fixture ID is unavailable; validate update
acknowledgements with contactsUpdate and fetch the contact afterward to assert
first_name. In the cancellation test, use a scheduled email fixture and send
POST to emails/{id}/cancel instead of selecting an arbitrary email or using the
wrong request.
In `@packages/resend/endpoints/types.ts`:
- Around line 238-243: Handle contact mutations as acknowledgement responses:
map contactsUpdate to ContactsMutationResponseSchema, fetch the complete contact
before persistence, and persist that full entity rather than a placeholder with
an empty email. Apply the contacts.get persistence fix in
packages/resend/endpoints/contacts.ts:24-29 and
packages/resend/endpoints/contacts.ts:114-119, update the schema in
packages/resend/endpoints/types.ts:238-243, and adjust
packages/resend/api.test.ts:319-332 to assert the mutation ID, then fetch the
contact and assert first_name.
In `@packages/resend/webhooks/domains.ts`:
- Around line 115-123: Extend the ResendDomain.status definition in
packages/resend/schema/database.ts to include partially_verified and
partially_failed, matching DomainStatusSchema and the endpoint schema. Remove
the duplicated inline status casts at packages/resend/webhooks/domains.ts lines
115-123 and 43-51, and packages/resend/endpoints/domains.ts lines 47-55 and
93-101, relying on the shared ResendDomain.status type instead.
In `@packages/resend/webhooks/types.test.ts`:
- Around line 7-33: The test signing setup around signSvix and
verifyResendWebhookSignature uses an incorrectly prefixed key; provide the
verifier with the decoded secret material while preserving the whsec_ form only
where the signing helper requires it. Restore coverage for valid sha256=

the fallback behavior unless the implementation explicitly drops backward
compatibility.

Resend API reference create contact response id get update delete contact response fields scheduled email cancel endpoint
💡 Result:
The Resend API provides endpoints for managing contacts and scheduled emails. Contacts API The Contacts API allows you to create, retrieve, update, and delete contacts [1][2][3][4]. Contacts are identified by a unique ID [1][5]. Create Contact: Sends a POST request to /contacts. The response includes an object type (typically "contact") and the unique contact ID [1][6]. Get Contact: Sends a GET request to /contacts/{id} (or by email). It returns contact details including id, email, first_name, last_name, created_at, unsubscribed status, and custom properties [2][5][6]. Update Contact: Sends a PATCH request to /contacts/{id} (or by email). The response typically confirms the update [3][6]. Delete Contact: Sends a DELETE request to /contacts/{id} (or by email). The response indicates the id of the deleted object, the object type, and a deleted status [4][6]. Scheduled Email API Scheduled emails can be managed via the Emails API [7][8]. Cancel Endpoint: To cancel a scheduled email, send a POST request to /emails/{email_id}/cancel [7][8][9]. Response: The response typically confirms the cancellation by returning the ID of the canceled email object [7][10]. Contact Response Fields When retrieving or listing contacts, the standard fields returned include [5][6]: - id: The unique identifier for the contact. - email: The contact's email address. - first_name: The contact's first name. - last_name: The contact's last name. - created_at: The timestamp of when the contact was created. - unsubscribed: A boolean indicating global subscription status. - object: The type of object (e.g., "contact"). - properties: A map of custom key-value pairs associated with the contact [6].

Preserve the contact fixture for the lifecycle tests.
Resend returns a contact ID, not testContactEmail. The assertion at line 261 fails.
Store result.id, move cleanup to afterAll, and fail the get, update, and delete tests when the fixture is missing. This applies to lines 294-296, 315-317, and 342-344.
The update response is an acknowledgement. Assert it with contactsUpdate, then call get to assert first_name.
The cancellation test selects an arbitrary email and uses the wrong request. Use a scheduled email and POST /emails/{id}/cancel.

Resend API create contact response id format contacts create-contact documentation UUID contact_ prefix
💡 Result:
When you create a contact using the Resend API, the response returns an ID field containing a standard UUID (Universally Unique Identifier) [1][2][3]. The Resend API does not use a "contact_" prefix for its contact IDs [1][2]. The confusion likely stems from other services (such as SendX) that utilize a prefixed ID system (e.g., "contact_xxxxxxxxxxxxxxxxxxxxxx") [4][5][6]. In Resend, the contact creation response follows this format: { "object": "contact", "id": "479e3145-dd38-476b-932c-529ceb705947" } The "id" is a standard UUID string [1][2]. You can find full implementation details for creating contacts in the official Resend API documentation [1][2].

Accept UUID contact IDs instead of requiring contact_.
Resend returns a UUID-style id, so /^contact_/ rejects valid responses. Assert that result.id is a non-empty string. The lifecycle tests currently locate the contact by email, so remove the cleanup comment unless they use result.id.

In `@packages/resend/api.test.ts` around lines 271 - 272, Update the assertion in
the Resend result test to verify that result.id is a non-empty string rather
than requiring a contact_ prefix, and remove the cleanup comment if result.id is
not used for cleanup since lifecycle tests locate the contact by email.
