Test entire API flows,
not just endpoints
Connect endpoints in a visual graph and let responses flow automatically from one request to the next — login, create, fetch, delete, all in one chain.

How it works
Build a chain once, run it any time — manually, on a schedule, or after each deploy.
Add endpoints to the graph
Drag any saved endpoint onto the canvas. Each becomes a node with its method, path, and configuration.
Connect them with lines
Draw a connection from one node's output port to the next. This defines the execution order and allows branching.
Map response fields
Select which field from the response (e.g. token, user_id, workspace_id) should be injected into the next request as a header, param, or body value.
Run and verify
Click Run chain. Each node executes in order, assertions are checked, and any failure stops the chain with a clear error.
Response field mapping
Pick any value from a response and bind it automatically to the next request.
Mappings are defined visually — no code required.
Everything you need
Chained requests
Connect endpoints in a visual graph. The output of one request automatically feeds into the next — no copy-pasting tokens or IDs.
Branching flows
One endpoint can fan out to multiple parallel branches — run two GET endpoints simultaneously off the same POST response.
Status code assertions
Each node asserts the expected HTTP status. If any step returns an unexpected code, the chain stops and alerts you immediately.
Response field mapping
Pick any field from a response — token, id, slug — and bind it to a header, query param, or body field in any downstream endpoint.
Common chain patterns
Real flows your team is already testing — now automated.
Auth → Protected route
Login first, pass the token, hit a secured endpoint
Create → Read → Delete
Full CRUD lifecycle verified end-to-end
Create → parallel reads
One create feeds multiple GET endpoints simultaneously
Multi-step checkout
Cart → Order → Payment → Confirmation in sequence
Upload → process → verify
File upload, background processing, result check
Full onboarding flow
Register → Verify → Profile → Workspace → Invite
