When integrating avatar analysis services into your application, the quality of your input data is the primary factor in reducing processing errors. Whether you are performing a single-identifier check for WhatsApp or submitting a large batch task for Telegram or Viber, "garbage in, garbage out" is a reality that can lead to unnecessary billing for undetermined results or failed requests.
Understanding the Integration Boundary
Before data crosses the boundary from your application to an analysis service, it must be normalized. Different services have specific requirements for identifiers:
- Realtime Checks: Limited to specific messaging and email providers (e.g., WhatsApp, Gmail, Yandex, Mail.ru).
- Bulk Tasks: Support a wider range of sources like Telegram, Viber, LINE, Zalo, and MAX. These require TXT or CSV files containing exactly one identifier per line.
- Image Analysis: Requires either a direct file upload or a public HTTPS URL pointing to a supported format (JPEG, PNG, WEBP, or GIF).
The Normalization Checklist
To ensure your input is ready for analysis, implement a pre-processing layer that enforces these rules:
- Format Constraints: If you are preparing a bulk task, reject any input that is not a plain TXT or CSV file. Do not attempt to upload XLSX or other proprietary spreadsheet formats, as these will not be processed.
- Identifier Sanitization: Strip all leading/trailing whitespace from identifiers. Ensure that phone numbers follow the expected international format without extra symbols that might cause a lookup failure.
-
URL Validation: For image analysis, verify that the provided URL is publicly accessible and uses the
httpsprotocol. Private or authenticated URLs will result in an error. - Data Minimization: In line with GDPR Article 5(1)(c), only send the identifiers necessary for your specific task. Avoid batching unnecessary metadata or PII that the service does not require.
Rejection Examples
Your application should catch these common issues before they reach the API:
- Malformed Identifiers: A list containing multiple identifiers on a single line will cause the bulk processor to fail on that row.
-
Unsupported Protocols: Providing an
httpURL instead ofhttpsfor image analysis will result in a connection failure. - Spreadsheet Bloat: Attempting to pass an Excel file instead of a clean CSV will result in an immediate rejection at the integration boundary.
Choosing Your Integration Path
| Feature | Realtime Single Check | Bulk File Task |
|---|---|---|
| Best For | Immediate user feedback | Large contact list processing |
| Input Format | Single identifier/URL | TXT or CSV (one per line) |
| Supported Sources | WhatsApp, Email (Gmail, Yandex, Mail.ru) | WhatsApp, Telegram, Viber, LINE, Zalo, MAX, Email |
Conclusion
By implementing a robust normalization layer, you ensure that your requests are compliant with the service's requirements. Remember that avatar analysis provides algorithmic estimates and public profile signals—it is not a tool for identity verification or KYC. Always treat the results as auxiliary references rather than definitive demographic facts. For specific details on file-size caps and entry limits, consult the official documentation.
