belongs to, the template name, language, and components like header, body, and buttons ensure these values are present and correctly formatted in the payload when using the api curl step 5 create a csv file with one column containing the phone numbers of the users you want to target for the broadcast the header of this column must be labeled as "user phone number" if your message template includes any variables or placeholders for additional user attributes, you'll need extra columns in the csv the headers for these extra columns should follow the format "user attribute n" where n starts from 0 and increments for each attribute (e g user attribute 0, user attribute 1, user attribute 2, and so on) step 6 open you postman and enter the values as mentioned below method post

and api key, navigate to integrations > engati api to generate an api key click on "+create app" step 7 in the headers field enter the below mentioned key and value authorization basic \<api key> content type application/json step 8 in the body enter the below mentioned key and value for version 1 target audience provide the csv file containing the list of recipients that you created in step 5 template payload include the structure of the message template you want to send, along with any necessary parameters this template payload should be the same payload section obtained from the generated api curl in step 4 in the body enter the below mentioned key and value for version 2 target audience provide the csv file containing the list of recipients that you created in step 5 payload we have added additional details like broadcasttitle, platform, countrycode and along with that, include the structure of the message template you want to send, along with any necessary parameters this template payload should be the same payload section obtained from the generated api curl in step 4 after completing all the previous steps mentioned above, including providing the target audience csv file and template payload details, you can initiate the external broadcast by clicking the "send" button this will trigger the api call and kick off the process of sending the broadcast message to the specified list of recipients using the provided template sample curl request version 1 curl location request post 'https //api engati com/whatsapp api/v1

allows you to provide the specific data and recipient information to be used in conjunction with the message template payload for version 2 , we support the same csv structure that we support for ' import contact list' on our platform column headers the first column header in the csv file must be "user phone number," as a phone number is mandatory for whatsapp as the broadcast channel beyond the phone number column, there will be additional column headers for any attributes or placeholders used in the template message these columns will follow the format "user attribute n," where n starts from 0 and increments for each subsequent attribute (e g , user attribute 0, user attribute 1, and so on) phone number to ensure that the phone number is in the correct format, it is necessary to include the "+" symbol followed by the country code preceding the phone number itself this standardized formatting is crucial for the successful delivery of the broadcast messages response codes when using the external broadcast api, it's important to be aware of the various response codes that may be returned some common response codes include 1000, "success" indicates that the api call was successful 2000, "failure" an unhandled error occurred during the process 2003, "bot not found" the provided botkey does not match any engati bot 2004, "api key not found" the 360dialog configuration is not set up correctly 2005, "invalid file format" the uploaded file is not in the expected csv format 2006, "file upload failed" there was an error during the csv file upload, or the file size exceeds the allowed limit by adhering to the csv file structure guidelines, including the correct column headers, phone number formatting, and attribute columns, you can effectively leverage the external broadcast api to send personalized messages to your target audience understanding the potential response codes can also aid in troubleshooting and ensuring a smooth broadcast experience if
