Request Status

Retrieve the status and results of a verification request by its ID. Use this endpoint to poll for results if you’re not using webhooks.

Overview

After submitting a verification request, you receive a request ID. Use this endpoint to:

Check the current status of a request
Retrieve verification results when completed
Get error details if the request failed
Verify webhook delivery status

Request

Path Parameters

string

required

The unique request ID (UUID) returned when the verification request was submitted.

  "error": "Unauthorized"
}

404 Not Found

{
  "statusCode": 404,
  "message": "Request not found",
  "error": "Not Found"
}

Polling Best Practices

When polling for results:

Use Exponential Backoff

Start with 1-2 seconds, increase delay progressively

Set a Timeout

Don’t poll indefinitely - set a maximum duration

Prefer Webhooks

Webhooks are more efficient than polling

Check Terminal States

Stop polling when status is COMPLETED, FAILED, or PARTIAL

Example Polling Implementation

async function pollForResult(requestId, maxAttempts = 30, initialDelay = 1000) {
  let attempt = 0;
  let delay = initialDelay;
  
  while (attempt < maxAttempts) {
    const response = await fetch(
      `https://api.txncheck.in/api/v1/requests/${requestId}`,
      { headers: { 'X-API-Key': API_KEY } }
    );
    
    const data = await response.json();
    
    // Check for terminal states
    if (['COMPLETED', 'FAILED', 'PARTIAL'].includes(data.status)) {
      return data;
    }
    
    // Wait before next attempt
    await new Promise(resolve => setTimeout(resolve, delay));
    
    // Increase delay (max 10 seconds)
    delay = Math.min(delay * 1.5, 10000);
    attempt++;
  }
  
  throw new Error('Polling timeout - request still processing');
}

// Usage
try {
  const result = await pollForResult('550e8400-e29b-41d4-a716-446655440000');
  console.log('Verification result:', result);
} catch (error) {
  console.error('Polling failed:', error.message);
}
