Running a Bulk WhatsApp Avatar Check from Upload to Export
Checking one number is trivial; checking a hundred thousand and getting a file your operations team can actually use takes a little planning. This walks the whole path, from preparing the upload to handing over the export.
A bulk run of the Whatsapp Avatar, Age, Gender & Others Checker follows four steps: prepare the number list, submit it through the dashboard or the API, wait for the batch to complete, then export the enrichment columns next to your original rows.
Prepare the list before you upload it
Two things save the most time later. First, deduplicate — paying to check the same number twice is the most common avoidable cost in a bulk run. Second, keep a stable row identifier from your own system in the file, so the export can be joined back to your records without matching on the phone number itself.
Submit through the dashboard or the API
The dashboard suits one-off runs and gives you a visible task list. The API suits recurring runs that another system triggers. Either way you select the Whatsapp Avatar, Age, Gender & Others Checker explicitly, because each checker is scoped to its own platform and its own documented fields.
Read the export without over-reading it
The export tells you which numbers have WhatsApp account presence and what profile enrichment was available at check time. It does not tell you who controls a number or whether anyone will reply. Writing that sentence into the handover note is worth the ten seconds — it is the single most common misreading of an enrichment file.
Decide what happens to blanks
Some accounts expose no avatar or demographic fields at all, so blanks are expected and are not failures. Agree in advance whether blanks route to a lower-priority queue, get re-checked later, or are simply left alone, so the same file does not get interpreted three different ways by three teams.
FAQ
How large a list can I submit at once?
Batch sizes are documented per checker rather than shared across products, so check the limit for the specific checker you are running before splitting a very large file.
Can the export be joined back to my CRM automatically?
Yes, provided you kept your own row identifier in the uploaded file. Joining on that identifier is more reliable than joining on the phone number.
