No-Code / Low-Code API Integration

Connect internal and external APIs with visual workflows so teams can build and change integrations without writing code.

Practical use cases

Concrete ways teams use Zerq for this scenario.

  • Let product or ops build “when X happens, call API Y” flows

    A business user designs a workflow: when a request hits a path, call an internal or external API, branch on the response, and return or trigger another step. No code deploy—publish the workflow and it’s live. Changes are audited so you know who changed what.

  • Map fields and shape responses in the UI

    Use step outputs and custom response nodes to pick fields from one API and build the JSON you return to the client. When the upstream API changes, you adjust the workflow instead of editing application code.

  • Add a code node only when you need it

    Most steps are visual (HTTP call, branch, response). For complex parsing or logic, add an optional code node. The rest of the flow stays no-code and the whole workflow is still versioned and audited.

Outcomes

  • Faster integration delivery: product and ops can build and tweak flows without developer deployment.
  • Fewer custom integration services to maintain; one platform for gateway and integration logic.
  • Clear visibility and audit for compliance and troubleshooting.

How Zerq helps

  • Workflow designer is the primary integration surface: add HTTP/backend call nodes, conditional branches, and custom response nodes; reference data from previous steps so you chain and map without code.
  • No-code flows for common patterns: validate → call backend → branch on status → return or retry; field mapping via step outputs and custom response body (e.g. JSON built from step data).
  • Low-code escape hatch: optional code node for complex mapping, parsing, or logic; keeps most integrations code-free while allowing power users to extend where needed.
  • Environment-referenced secrets and credential encryption so API keys for SaaS and partners stay out of workflow config; RBAC so only authorized users can edit integrations.
  • Full audit trail of workflow changes and API usage; structured logs so you can debug integration issues without reading application code.
For architects & evaluators (technical context, requirements)

Technical context

Integrating APIs and systems usually means writing and maintaining code: HTTP clients, mapping, error handling, and deployment. That creates a bottleneck (only developers can change integrations) and slows down partner onboarding and internal automation. A no-code or low-code approach lets product and ops teams design integrations in a visual workflow: define steps (call API A, then B, branch on result, return response), map fields in the UI, and publish—with an optional code node only when custom logic is truly needed.

Technical requirements

  • Visual design of integration flows: steps, branches, and data flow without writing code.
  • Call external and internal APIs from workflow steps; pass request/response data between steps.
  • Field mapping and simple transforms in the UI where possible (e.g. pick from previous response).
  • Optional script or code node for expressions or one-off logic when visual nodes are not enough.
  • Secure storage of API keys and secrets; audit trail of who changed which integration.
