When there is a data sheet validation failure after uploading the contacts Excel sheet, it is recommended to download the sample file available in Step 4. Once downloaded, simply follow the pre-existing format of the sample sheet and copy over your contacts’ data.

The most common error fixes are as follows:

1. The heading for the contact numbers is case-sensitive. The heading should always be “phone” and not “Phone.”
2. Headings are also whitespace-sensitive.
3. If your template has variables, the variables should be listed in consecutive columns with accurate variable headings.

If you’re testing the campaign message to your number in Step 5 and it failed, this is most likely due to Frequency Capping. You can read all about this guideline by Meta here: https://scribehow.com/page/Frequency_Capping__vZJC0_nURcGE9nvBNbZQww

A quick fix is to send a “Hi” message to your WhatsApp bot from the test number and then try sending the test message again.

To ensure this problem does not persist, we recommend interacting with your WhatsApp bot after every three messages.

If you are unable to upload any media during the creation of a campaign, please note the following points:

1. Images should be less than 5MB.
2. Images should in either JPEG or PNG format.
3. Videos should be in mp4 format and be less than 15MB. The recommended resolution is 940 x 500 pixels.

Note: Images taller than 1.91:1 aspect ratio are cropped vertically. To communicate the crux in such images, plan to present the most important information at the center of the image.
