Optional collection metadata & Kenya docs polish

Pass optional metadata on collect-money and receive the same array back on create responses and webhooks. OpenAPI, Postman, AI skill, PDF, and sandbox docs now cover Uganda and Kenya clearly.

API
  • POST /collect-money and POST /send-money accept optional metadata (max 10 objects; each one field + value, optional isPII)
  • Metadata is returned on create as data.collection.metadata / data.withdrawal.metadata and on callbacks as top-level metadata
Docs
  • OpenAPI country enum UG|KE with Kenya collect/send examples
  • Postman Kenya M-Pesa collect and send examples
  • AI skill and PDF guide cover Uganda + Kenya markets
  • Sandbox docs clarify merchant metadata vs response diagnostics (data.metadata)
  • Send-money, Kenya, Webhooks docs updated for disbursement metadata
  • Callback docs: top-level metadata on collect/send success and failure (webhooks guide, Kenya, PDF, AI skill)

  • Integration tools page — OpenAPI spec, Postman collection, and AI integration skill (SKILL.md)
  • Downloadable integration guide (PDF) with clickable table of contents
  • Public changelog for API and documentation updates
API
  • API errors now return specific, client-safe messages (e.g. VALIDATION_ERROR, DUPLICATE_REFERENCE, FORBIDDEN) instead of generic SERVER_ERROR where possible
