Integrations

Tendrex integrates with external tools through its public REST API, webhooks, and upcoming no-code connectors.

Available now

Section titled “Available now”

REST API

Section titled “REST API”

The Tendrex public API provides full programmatic access to tenders, answers, documents, the knowledge library, and more. Use it to build custom integrations with your CRM, reporting tools, or internal systems.

  • Bearer token authentication with scoped API keys (read, write, admin)
  • Rate limited at 100 requests per minute per key
  • OpenAPI 3.0 specification available at /api/v1/openapi.json

Webhooks

Section titled “Webhooks”

Event-driven webhooks push real-time notifications to your systems when things happen in Tendrex — tenders created, answers approved, documents uploaded, and more.

  • 15+ event types across tenders, answers, compliance, users, and documents
  • HMAC-SHA256 signatures for payload verification
  • Automatic retries with delivery tracking
  • Wildcard subscriptions (* for all events, tender.* for all tender events)

Coming soon

Zapier

Section titled “Zapier”

A native Zapier connector will allow you to connect Tendrex to 6,000+ apps without writing code.

Planned triggers:

  • New tender created
  • Answer approved or rejected
  • Tender status changed
  • Tender submitted
  • Document uploaded
  • Compliance item updated

Planned actions:

  • Create a tender
  • Add a question to a tender
  • Query the knowledge library
  • Upload a document
  • Invite a user

Example workflows:

  • When a tender is awarded in Tendrex, create a project in Asana and notify the team in Slack.
  • When a new tender is created in your CRM, automatically create a matching tender in Tendrex.
  • When answers are approved, push them to a SharePoint folder for archive.

Power Automate

Section titled “Power Automate”

A Microsoft Power Automate connector will bring Tendrex into your Microsoft 365 workflows.

Planned triggers and actions mirror the Zapier connector above, with additional support for:

  • Microsoft Teams notifications — post to a channel when tenders are created, answers need review, or deadlines approach.
  • SharePoint integration — sync documents between SharePoint libraries and the Tendrex knowledge base.
  • Outlook tasks — create tasks when questions are assigned to you.
  • Excel Online — export tender data and analytics to Excel workbooks automatically.

Example workflows:

  • When a tender deadline is 7 days away, post a reminder in the bid team’s Teams channel.
  • When a document is added to a SharePoint folder, automatically upload it to Tendrex.
  • When a tender is submitted, send a summary email to stakeholders via Outlook.

Building custom integrations

Section titled “Building custom integrations”

If you need an integration that isn’t covered by the connectors above, use the public API and webhooks directly. The OpenAPI specification at /api/v1/openapi.json can be used to generate client libraries in most languages.
