Webhooks API · deliveries
Send one of the calling app's deliveries again
POST /deliveries/{deliveryId}/redeliver
Send one of the calling app's deliveries again, now — a failed one once the app is fixed, or a delivered one it lost.
The same event id, so the app recognises it. Appends nothing: a delivery is the dispatcher's execution state, not a fact of the organization's. No idempotency key: redelivering is meant to send again, and a second call only queues the same event once more.
Access
Requires a signed-in session: an app token: subscriptions and their deliveries belong to the calling app alone, and each topic is held to its own grant
Send Authorization: Bearer $APP_TOKEN.
How scopes come from roles: Scopes and roles. Getting a token: Authentication and app tokens.
Retries
No idempotency key: redelivering is meant to send again, and a second call only queues the same event once more.
Why every write carries a key: Idempotency and retries.
Facts appended
None. This call records nothing in a journal.
What a fact is: Facts and the journal.
AI agent tool
No agent tool. An app's webhook plumbing — its subscriptions, delivery log and signing secret — answers that app's own token alone; an agent acts as a person and reads what happened through the journals' tools instead.
Connecting an agent: AI agents.
Example
A failed delivery queued again: it is tried at once, its earlier attempts kept.

}The panel writes this call in other languages. It does not send it: Manifold's APIs do not take calls from a web
page on another site, so run the call from your own code or terminal. The whole API as OpenAPI: webhooks.openapi.json. Base URL https://webhooks.getmanifold.io.
Errors
Every refusal is a status and a JSON body whose _tag names it. A refused call changes nothing.
401
| Refusal | What it means | What to do |
|---|---|---|
Unauthorized reason | The token is missing, expired or not one Manifold issued. | Get a fresh token and send the call again. |
TokenAlreadyUsed tokenId | A single-use app token was already spent. | Mint a new token for this call. |
402
| Refusal | What it means | What to do |
|---|---|---|

403
| Refusal | What it means | What to do |
