Webhook structure

All our webhooks will be sent with the following headers:

X-TL-Webhook-TimestampISO-8601 TimestampTime that the webhook was sent to you. This will be in the following format: 2020-05-18T10:17:47Z.
TL-SignaturestringJSON web signature with a detached payload of the form {HEADER}..{SIGNATURE}

All incoming webhook requests must have their signatures verified, otherwise you run the risk of accepting fraudulent payment status events. See Validate the received webhook signature.

The webhook body will be encoded in JSON format with the following fields:

typestringType of the event
event_idstringA UUID for the event
event_versionstringVersion of the event type

Each type of event may provide other fields. See the the specifications of the mandate or payment webhooks for more details.

For the best development experience, use our signing libraries to verify signatures.
