Suggested Flow

The collection is organized in typical usage order:

1. Auth → Generate Token — run this first. The response auto-saves access_token to an environment variable.
2. Balance → Get Balance — confirm the token works.
3. SPEI → Cash-In — create a simulated charge.
4. Transactions → List — check status.

​

Available Folders

• Auth — JWT generation
• Signup — account creation
• Balance — balance query
• SPEI — cash-in, cash-out, transaction by external ID
• OXXO — cash-in
• Transactions — list
• Webhooks Config — list, create, delete
