iGrant.io OID4VC API - Webhook group

When to use

Use this skill when you:

• register an external IT system to receive OWS events;
• must know the exact event type strings to subscribe to;
• verify the X-IGrant-Signature header on an incoming delivery;
• debug a receiver that gets no events, or reads a delivery record.

Base URL for demo: https://demo-api.igrant.io. Auth header: Authorization: ApiKey <key> (note the trailing space in the prefix). A bearer access token also works.

The webhook operations carry only the Webhook tag. They serve every building block, not the OID4VC wallet alone.
