Connect Square and Retell AI with AI-native workflow automation
Type an outcome. Definable Workflow reads Square data, applies your rules, and writes to Retell AI — end to end, in one multi-agent run. Builder plans every step, Executor calls each API, Verifier retries failures. Chain 1,000+ other apps in the same flow. Zero code, zero flowcharts, self-healing. Free on the Starter plan.

6 use cases Self-healing 1,000+ apps payment processing
Definable connects Square and Retell AI through a three-agent AI loop — Builder plans, Executor runs, Verifier self-heals. One plain-English prompt replaces every Zap, scenario, and cron. Setup takes under two minutes.
Square and Retell AI are two anchors of a much bigger automation. Definable Workflow chains your billing system, your AI layer, and as many other tools as the job needs into a single multi-step flow — built, executed, and verified by AI. Describe the outcome; Workflow plans the steps, runs every API call, branches on conditions, fans out in parallel where useful, retries on failure, and self-heals when an upstream API shifts shape.
6 ways to automate
What you can automate between Square and Retell AI
- When a payment succeeds in Square, route the output to the right system in Retell AI
- When a charge fails in Square, log the generation in Retell AI
- When a model output is generated in Retell AI, log the transaction in Square
- When a tool call completes in Retell AI, update the customer record in Square
- When a subscription renews in Square, trigger the next step in the chain in Retell AI, and log the result in a structured record for team review
- When an invoice is paid in Square, attach the result to a record in Retell AI, then send a notification to the assigned owner with the full context
Why Workflow
Most automation tools run code. Workflow runs on AI.
AI builds it AND runs it.
Other platforms use AI to generate brittle code that runs offline. Workflow's entire execution layer is AI — it interprets, decides, and acts step by step.
Self-healing by design.
Every step is monitored by a verification layer. If something fails — a rate limit, an unexpected response, a skipped condition — Workflow detects it, corrects it, and reruns automatically.
Cross-tool orchestration.
Multi-step, event-driven, condition-based flows across Square, Retell AI, and 1,000+ other tools — all from one instruction.
How it works
Four steps from prompt to running workflow
- 01
Describe your workflow
Type what you want to happen between Square and Retell AI. No setup wizard.
- 02
Workflow builds it automatically
Definable maps the instruction to the right actions across both tools. Review the plan before it runs.
- 03
AI executes every step
Workflow runs end-to-end. Calls Square, processes the data, applies conditions, and fires the Retell AI action.
- 04
Verification layer monitors everything
Every step verified. If something fails, Workflow catches it, adjusts, and retries — without any manual intervention.

Trigger → Condition → Action
Trigger

FAQ
Common questions about Square + Retell AI
What can I automate between Square and Retell AI?
Anything you can describe. Workflow connects Square (your billing system) and Retell AI (your AI layer) through a single instruction. Examples: when a payment succeeds in Square, route the output to the right system in Retell AI; when a charge fails in Square, log the generation in Retell AI. There's no limit to step count or branching depth.
Do I need to write code to connect Square and Retell AI?
No. You describe the outcome in plain language and Workflow assembles the steps, authenticates both tools, runs the flow end-to-end, and self-corrects if anything fails.
What happens if Square or Retell AI returns an unexpected response?
Workflow has a verification layer on every step. If a response is malformed, an API rate-limit hits, or a condition is unmet, Workflow detects it, adjusts, and reruns the step automatically — without breaking the flow.
How is this different from drag-and-drop automation tools?
Most automation tools generate static workflows that run brittle code. Workflow is AI-native: the execution layer interprets each step at runtime, so it adapts when Square ships an API change or Retell AI returns a new field shape. You don't maintain it.
How long does it take to set up?
Minutes. Authenticate Square and Retell AI, type what you want to happen, review the plan Workflow generates, and start running.
Workflows built, run, and fixed by AI.
Stop maintaining automations. Workflow handles everything between Square, Retell AI, and the rest of the stack.
