Why one endpoint matters
Most teams end up maintaining two flows: one for transactional email and another for WhatsApp notifications. That split creates duplicate validation, duplicate retries, and fragmented observability.
Zindua keeps a single contract around /api/v1/send so your backend can switch channel by changing one field instead of adopting a second SDK and second set of failure modes.
How delivery stays resilient
Incoming payloads are validated before entering queueing. Invalid template slugs, malformed phone numbers, and missing variables fail fast with clear errors.
Successful requests are queued with metadata that allows retries and tracing without leaking secret credentials into client code.
- Request validation before queue insert
- Unified status model across channels
- Traceable log IDs for each message
- Deterministic retries for transient failures
Operational outcomes for teams
A single API shortens onboarding for new engineers and reduces integration drift between products. Your support team gets one log stream instead of multiple disconnected tools.
From launch to scale, product teams keep one mental model while still sending through the channels users actually read.
