Integrations
API & webhooks and PayBlah
PayBlah API and signed webhooks for teams that need the chase to talk to the rest of their stack — scoped keys, same safety rails.
API & webhooks
Keep the chase list honest
Some teams need buttons. Others need events. PayBlah exposes a REST API with bearer keys and scopes, plus signed outbound webhooks so your other systems can react when something changes.
The same safety philosophy applies: the API is not a back door to skip stop-on-payment or blast every contact without the controls the product is built around.
Rate limits scale with plan. Details ship with product docs as the API surface stabilises for public launch.
What this is not
- Not an invitation to spam — Acceptable use still applies
- Not a promise of every internal endpoint forever; public surface is documented deliberately
- Not a replacement for connecting Xero/QBO/Sage when that is the simpler path
