API & Integrations: common questions
Can you integrate a tool that isn't on your list?
Almost certainly. If the tool has an API or webhooks, we can connect it. We check the documentation before quoting.
What happens if a third-party API is down?
We queue and retry failed calls and log every attempt, so nothing is lost when the service recovers.
Do you handle payment webhooks?
Yes, including signature checks, retries, and the edge cases around subscriptions and failed payments.
Will we get API documentation?
Yes. Every API we build comes with interactive Swagger documentation.
