## Which one, for what

### Payhawk API + MCP (C)

Good for: A finance team already on Payhawk that wants an ERP or accounting sync, master data kept in step, purchase orders raised from another system, or an assistant that answers spend questions and prepares approvals.

Ahead on:
- Reliability, 58 against 30
- Transparency & trust, 78 against 70

Also in its favour:
- No incidents deducted, where Ramp loses 3 points for them

Watch for: No self-serve route. The API needs a Payhawk customer account, and a development sandbox is requested through a form

### Ramp (C)

Good for: A finance team already on Ramp that wants an agent to read transactions, upload receipts, code and split expenses, issue funds with limits, create bills and work with purchase orders and procurement requests.

Ahead on:
- Schema & documentation, 86 against 71
- Agent ergonomics, 66 against 52
- Security & auth, 79 against 71
- Payments & pricing, 25 against 13
- Maintenance & community, 74 against 53

Watch for: No public status page was found. status.ramp.com doesn't resolve, and no status link appears in the docs, help centre or trust centre pages read

## Verdicts

**Payhawk API + MCP.** The Developer API has a public OpenAPI 3.1 definition with 179 operations, read-only or full-access keys and a published limit of 15 requests a second. It needs a Payhawk customer account, no official SDK or API changelog was found, and the 82-tool MCP server is added by hand because it is not yet in the assistant directories.

**Ramp.** OAuth 2.0 scopes split read from write across about 40 resources, a 260-operation OpenAPI spec is public, and an audit log endpoint records actions by user and agent. No public status page was found, 89 operations are marked beta, the API Agreement allows changes without notice, and idempotency keys cover only eight write operations.

## Before you call either

### Payhawk API + MCP

1. Send the key in `X-Payhawk-ApiKey` or as a Bearer token to `https://api.payhawk.com/api/v3`. A read-only key returns 403 on writes
2. Page lists with `$skip` and `$take`. The help centre gives 1,000 a page and the definition a maximum of 10,000, so count what comes back
3. Pass `$filter` as URL-encoded JSON, for example `{"status":{"$equal":"draft"}}`. Date filters compare the date part only
4. Keep to 15 requests a second and wait for `Retry-After` on a 429. Do not send `Idempotency-Key` when creating a per diem expense, which returns 400
5. Use a group-level key and the `/groups/{groupId}` paths for master data in a multi-entity group. Expenses and payments stay on account paths

### Ramp

1. Send `scope` on the client credentials token request. Without it Ramp issues a token with no scopes and every resource call fails with 403
2. Follow the full URL in `next` to page. `page_size` defaults to 20 and stops at 100, and the cursor is opaque
3. Stay under 200 requests in any 10 seconds per source IP and back off 1, 2 then 4 seconds on 429. No Retry-After header is documented
4. Don't use `synced_after` or `from_created_at` to find changed records. Bills and transactions have no updated-at filter, so subscribe to webhooks
5. Send `X-Idempotency-Key` when creating funds or procurement requests. Elsewhere a retried POST can create a duplicate, so read back before retrying
