Hey everyone,
I’ve been building on Bubble for a while now and recently wrapped up a few projects that pushed the platform’s API capabilities pretty hard. Thought I’d share some real learnings since most posts I see on API integrations stop at the basics.
What I’ve built:
-
A client portal that pulls live data from a third-party CRM via API and displays it in real-time dashboards
-
An automation workflow connecting Bubble to OpenAI — users fill a form, AI processes it, result comes back into the app automatically
-
A multi-step onboarding flow that hits 4 different APIs (payments, email, SMS, document generation) in a single workflow chain
A few things I ran into that took me a while to figure out:
-
When chaining multiple API calls in one workflow, error handling is everything. If step 3 fails silently, your data ends up inconsistent with no way to trace it. I now always build a logging system into any multi-API workflow.
-
Bubble’s API Connector handles most things well, but authentication token refresh needs careful workflow design — especially for OAuth 2.0 flows where the token expires mid-session.
-
For AI integrations specifically, streaming responses don’t work natively in Bubble. You have to design around this — I use a polling approach with a “status” field on the database record.
Happy to answer questions or share more detail on any of these. Also open to feedback if others have solved these differently.
