Ramp Read-Only Connectivity Proof

Overview

Prove the smallest useful path: obtain a token without exposing it, call the current Developer API transaction surface with minimum scope, inspect the response envelope, and record a sanitized environment receipt.

Prerequisites

• Identify the Ramp application, environment, business entities, affected data and workflows, accountable owner, and rollback boundary.
• Read references/official-docs.md and re-check endpoint schemas, scopes, limits, and support status before a live operation.
• Use synthetic fixtures or Ramp sandbox until production access and business effects are explicitly approved.
• Prepare approved secret storage and a sanitized evidence location.

Current Contract

• The current Developer API path is /developer/v1; the production host is api.ramp.com and the sandbox host is demo-api.ramp.com.
• The quickstart obtains a token from /developer/v1/token and reads transactions with transactions:read.
• List responses use a data collection and page metadata; callers must follow the documented cursor rather than assume one page is complete.
• Most Ramp monetary values are integers in the smallest unit of the accompanying currency, subject to the endpoint schema.

Authentication

Acquire a server-side OAuth bearer token from /developer/v1/token using the approved grant and minimum transactions:read scope. Keep the client secret and token out of source, browser code, logs, and evidence.

Instructions

1. Resolve the target environment, app owner, grant type, transactions:read scope, and approved secret-store references.

2. Acquire the token using the current authorization flow; retain only expiry, scope names, environment, and a one-way token-instance identifier.

3. Request the smallest documented transaction page from /developer/v1/transactions, with no write scope and no production query wider than approved.

4. Validate status, content type, data, page metadata, transaction IDs, amount representation, currency, and x-trace-id; redact people and merchant details.

5. Test one denial using an ungranted operation or sandbox-only client, then save the sanitized pass/fail receipt and next cursor behavior.

Tool Discipline

• Use Glob to locate candidate code, manifests, fixtures, and evidence without widening scope.
• Use Grep to find relevant endpoints, fields, permissions, identifiers, errors, and stale assumptions.
• Use Read to inspect the smallest required local files and authoritative evidence.
• Use Write only for a new approved local draft, test, configuration, or evidence artifact.
• Use Edit only for a bounded approved change with a known rollback.
• Local file tools do not authorize a Ramp operation or replace owner approval.

Approval Boundaries

The application owner approves client use; the data owner approves any production transaction read. No write or scope expansion is part of this proof.

Output

An environment and grant record, sanitized token metadata, bounded transaction response shape, cursor observation, trace ID, negative test, and explicit go/no-go for further work.

Error Handling

Examples

Example 1

Prove sandbox connectivity with a two-record transaction page and a denied card-write attempt.

Example 2

Run an approved production read for one page, redact the payload, and preserve only shape, count, cursor, trace ID, and environment.

Validation

• The request uses /developer/v1 on the intended host.
• The token and client secret never appear in source, terminal history, logs, or evidence.
• The response parser handles an empty data list and a continuation cursor.
• The read and negative test match the approved scope boundary.

Resources

• Official documentation and contract notes
• Re-check the dated contract and current OpenAPI schema before any live request.
• Treat unresolved vendor behavior, authority, or financial state as a stop condition.
