Every POBO endpoint lives under `/api/v0/pobo` and needs an API key carrying the `pobo` permission. POBO is **partner-scoped**: there is no `userId` in any path, and every identifier you exchange is a prefixed reference id rather than an internal UUID. POBO routes through Paywho only. A Bridge-routed currency or rail is rejected with `400 ERRTXN_1001`. Success bodies are unwrapped; `userId` and `ownerUserId` are never returned. servers: - url: https://api-sandbox.endl.io description: Sandbox security: - apiKey: [] paths: /api/v0/pobo/senders/{senderId}: delete: tags: - Senders summary: Delete sender description: >- Delete a sender by its `snd_` reference id.
