ACH Pull Webhooks

New in v3: v2 has no equivalent.

Every step of an ACH pull is sent to the workspace's webhook endpoints that subscribe to the banking category. The envelope is the one every webhook uses (Webhooks). The details object is the pull in the v3 format: the same field names Get an ACH Pull returns, with TypeIDs for every id and money as an amount and its currency.

Event types​

Event typeWhen
ach_pull_createdThe pull was accepted. Its credit is pending while the grace period runs, and it can still be cancelled.
ach_pull_status_updatedThe pull moved to another status. details.status is the new one and details.previous_status the one it left.

ach_pull_status_updated is sent for each of these statuses:

statusMeaning
cancelledCancelled inside the grace period. Nothing is debited.
processingThe bank took the debit.
postedThe debit settled. The credit is still pending: the holder's bank can return it for days.
completedThe hold ended. total became available, less reserved when the workspace holds a reserve. A return can still follow.
failedThe bank refused the debit, or it was never made. The pending credit was dropped.
returnedThe holder's bank sent the debit back. return_code names the NACHA reason (R01, R10, …). The credit was dropped, or taken back out of the available balance if the pull had completed.

Webhooks are delivered at least once and can arrive out of order. Use details.status and the pull's updated_at from Get an ACH Pull as the source of truth.
