## API COVERAGE

Every stage of the sourcing lifecycle, covered.

The API mirrors the complete Purchaser workflow. Every stage is a first-class resource with full read/write access, so your integration can go as deep as your architecture requires.

01

### Sourcing Setup

`/rfqs`

Create RFQs programmatically from ERP requisition data. Add line items, attach specifications, select vendors from your roster, and publish—all without manual re-entry between systems.

02

### Vendor Engagement

`/vendors` `/conversations`

Manage vendor profiles, contacts, and custom attributes. Each vendor's engagement on an RFQ is a first-class conversation resource—retrieve messages, track submissions, and send communications programmatically.

03

### Quote Evaluation

`/quotes`

Access structured quote data with full revision history and line-item detail. Create side-by-side comparisons calibrated to your requirements and export results to PDF or Excel.

04

### Documents & Files

`/files`

Attach specifications, drawings, and supporting documents to RFQs, vendors, and conversations. Upload via pre-signed URLs or direct proxy and generate download links for retrieval.

05

### Award & Downstream Sync

`/webhooks`

Register webhook endpoints so downstream systems stay in sync. Purchaser fires events when submissions arrive, evaluations complete, or awards are made—no polling required.

## INFRASTRUCTURE

Enterprise-grade API infrastructure.

### Authentication

API keys scoped to team and environment. Rotate keys without downtime.

### Rate Limiting

Sliding window rate limits with standard headers for client-side handling.

### Versioning

Versioned endpoints (/api/v1/) with additive-only changes. No breaking updates.

### Documentation

OpenAPI 3.1 spec with interactive explorer. Every endpoint documented with examples.

### Idempotency

Safe POST retries with idempotency keys. No duplicate resource creation.

### Debugging

Request ID in every response header. Trace any call through support.

## INTEGRATION TARGETS

Designed for the systems your teams already run.

The API connects Purchaser to ERP, PLM, project controls, and procurement platforms. Requisition data flows in, structured evaluation results flow out, without manual re-entry between systems.

|  | Manual process | With Purchaser API |
| --- | --- | --- |
| Requisition → RFQ | Copy-paste requisition data from ERP into email | Programmatic RFQ creation from ERP requisition data |
| Vendor data | Maintained separately in procurement tool and ERP | Single source, synced bidirectionally via API |
| Evaluation results | Exported as PDF, emailed to stakeholders | Structured data returned to ERP or BI systems |
| Quote tracking | Manual spreadsheet updates from email attachments | Webhook notifications when new submissions arrive |
