​
Error schema

All errors follow a standard shape: { error, message, status }. See Errors.

​
Common cases

  • 401 Unauthorized: missing/invalid token
  • 402 Payment Required: trial limit reached
  • 403 Forbidden: action not allowed
  • 409 Conflict: duplicate idempotency key or non-cancellable message
  • 503 Service Unavailable: no active devices

​
Retry strategy

Use an Idempotency-Key with exponential backoff for transient errors (5xx). 
import fetch from 'node-fetch'

async function postWithRetry(url, body, { maxAttempts = 5 } = {}) {
  let attempt = 0
  while (attempt < maxAttempts) {
    attempt++
    const idempotencyKey = `retry-${Date.now()}-${attempt}`
    const res = await fetch(url, {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${process.env.BLOOIO_API_KEY}`,
        'Content-Type': 'application/json',
        'Idempotency-Key': idempotencyKey
      },
      body: JSON.stringify(body)
    })
    if (res.ok) return res.json()
    if (res.status < 500) throw new Error(`Non-retryable: ${res.status}`)
    await new Promise(r => setTimeout(r, Math.min(1000 * 2 ** attempt, 10000)))
  }
  throw new Error('Max retry attempts reached')
}
Persist keys client-side to dedupe across restarts.
