Errors

Every Kirisan API response is JSON. Successful calls include "status": true. Failures include "status": false and a human-readable "reason" when the whole request failed before channel delivery.

HTTP status codes

Status	When it happens
200	Request parsed — check "status" in the body (send may return 200 with "status": false and channel details)
400	Invalid JSON, missing fields, or validation error
401	Missing or invalid Bearer token
403	Bearer token valid but a channel key does not belong to your account
503	Service temporarily unavailable

POST /v1/send usually returns HTTP 200 even when delivery fails — read "status" and "channels".

Top-level reason

These appear on the response root when the request never reached delivery, or when every channel failed in a blocking way:

Reason (examples)	Meaning
missing api token / invalid api token	Fix Authorization: Bearer … — see Authentication
invalid JSON	Body is not valid JSON
No channels configured	keys is empty — include at least one channel token
content required	No content object with at least one channel
no sendable channels: content requires a matching key	You set content.whatsapp but omitted keys.whatsapp, or similar
Invalid schedule: the time is in the past.	context.timing.schedule must be a future Unix timestamp
whatsapp key does not belong to this account	Channel token belongs to another user (403)

Validation errors from message bodies are also returned as top-level "reason" before send — for example email inline messages are not supported on /v1/send or waba message type must be text, interactive, image, video, or document.

Per-channel errors (channels)

On POST /v1/send, each channel you attempted has its own object under "channels":

{
  "status": false,
  "channels": {
    "whatsapp": {
      "status": false,
      "reason": "template is not approved for sending",
      "processing_time": "142ms"
    },
    "email": {
      "status": true,
      "processing_time": "891ms"
    }
  }
}

Field	Meaning
status	true if that channel delivered (or was scheduled)
reason	Present when status is false — quota, missing target, template inactive, provider error, etc.
detail	Extra provider payload on some channels (WhatsApp, Telegram, WABA)
processing_time	How long the provider call took
scheduled	true when the message was queued for context.timing.schedule
fallback	true when this channel sent as part of a fallback tier

When one channel fails and another succeeds (for example WhatsApp fails, email fallback succeeds), top-level "status" may still be true if any channel delivered.

Template errors on send

When content.<channel>.template points to a dashboard template that cannot send:

Reason	Meaning
template is not approved for sending	Template is still pending review or was rejected
template is inactive	Template exists but is turned off in the dashboard
WhatsApp template not found	Wrong ID, wrong channel, or template belongs to another account

Create templates under Channel → channel → Templates and confirm they are Approved and Active before referencing their ID on send.
