The response returns a `snd_` reference id — that is the `senderId` every POBO transaction requires. ## OpenAPI ````yaml api-reference/endl-pobo-api.json POST /api/v0/pobo/senders openapi: 3.1.0 info: title: Endl POBO API version: '0' description: >- Payment on behalf of — pay out on behalf of a named originator. 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`. servers: - url: https://api-sandbox.endl.io description: Sandbox security: - apiKey: [] paths: /api/v0/pobo/senders: post: tags: - Senders summary: Create sender description: >- Create a POBO sender — the originator a payment is made on behalf of. `type` is `INDIVIDUAL` or `BUSINESS`; a business carries its name in `businessName`. **Before a sender can be used for a payout it needs a name, a `governmentId`, and `address.country`.** A duplicate `governmentId` for the same partner is rejected with `409`.
