Secure API Proxy for Bubble.io API Connector
Shield Sensitive API Credentials in Bubble Apps and Workflows
To prevent API keys from leaking through the Bubble.io API Connector, route high-value third-party requests through RealComposer. RealComposer stores credentials encrypted at the edge and filters bloated responses, reducing the payload size that Bubble servers must parse.
Bubble API Connector Key Visibility Risks
In Bubble.io, shared team editors can see plaintext keys in the API Connector plugin tab, and client-side executed calls can expose headers to the browser console. Furthermore, Bubble charges for Workload Units (WU) when parsing massive third-party JSON payloads.
- Team collaborators inspecting production keys in the Bubble editor
- High Workload Unit (WU) consumption when Bubble parses 100+ unneeded fields
- Exposed credentials during browser network debugging
How RealComposer Solves This at the Edge
Configure Keys in Secret Vault
Keep master API keys out of Bubble and in RealComposer AES-256 vault.
Slim the Response for Bubble
Use the Visual Field Picker to extract only the 3-5 fields Bubble needs.
Call RealComposer in Bubble API Connector
Initialize call in Bubble pointing to your clean edge URL.
{
"id": "in_123",
"amount_due": 4900,
"status": "paid",
"hosted_invoice_url": "https://invoice.stripe.com/123"
}
{
"invoiceId": "in_123",
"amountDue": 4900,
"status": "paid",
"hostedUrl": "https://invoice.stripe.com/123"
}
curl -X GET "https://realcomposer.com/v1/acme/bubble-invoice?invoiceId=in_123"
Developer Questions & Troubleshooting
Does trimming JSON save Bubble Workload Units?
Yes. Bubble consumes compute based on payload volume and JSON complexity. Slimming payloads by 80%+ reduces WU consumption.
