Azure API Management vs Postman
API management head-to-head for ERP teams: evidenced capabilities, published pricing, and which ERPs each actually integrates with.
| Starting price | Tiered subscription, plus a pay-per-call Consumption tier | From $9/user/mo (published) |
| Deployment | Cloud, Hybrid | Cloud |
| Company size | — | SMB, Mid-market, Enterprise |
| Stated ERP integrations | SAP | None listed |
| Vendor | Microsoft | Postman, Inc. |
Our take
Where Azure API Management leads
- Stronger evidenced coverage on 23 of the 33 capabilities where they differ (led by multi-protocol support and ai token quotas & cost attribution).
- Stated SAP integration the alternative doesn't list.
Where Postman leads
- Stronger evidenced coverage on 10 of the 33 capabilities where they differ (led by mock servers / sandboxes and automated api testing).
- Published pricing where the alternative quotes.
Where they differ
The 33 capabilities (of 47 in the API management taxonomy) where the evidence separates them, biggest gaps first. “Not evidenced” means our research found no public documentation of this capability — the vendor may still offer it. Confirm on a demo.
