Account & Reports

Know when Rain deploys a collateral contract on-chain and when daily BIN report files are ready to fetch.

These webhooks cover account-level events: collateral contract creation for Rain-managed programs, and BIN report file delivery for BIN-Sponsorship programs.

The following events are available:

Event	Description
contract.created	Rain creates a collateral contract for an approved user.
report.created	BIN report files have arrived for a BIN-Sponsorship program.

contract.created

Blockchain tenants only:

On blockchain tenants where each user posts their own collateral, Rain creates a collateral contract for each approved user. Pooled-collateral programs deploy a single contract at setup, so they do not receive a contract.created event per cardholder.

Rain sends this webhook whenever it creates a new collateral contract.

report.created

BIN-Sponsorship program only:

This section applies to BIN-Sponsorship Programs. Take note of this information if you are using a BIN-Sponsorship Program.

Rain sends the report.created webhook when the processor’s BIN report files arrive in Rain’s storage servers. Reports for the previous day are available at 3pm ET.

The webhook provides:

• The year, month, and day of the files that have arrived.
• The format of the BIN reports that have arrived from the processor
