Pass array as query parameter in Postman

Question

I am trying to pass an array as query parameter in Postman.

I am calling DELETE method to delete a user from list of databases. It is expecting list of database names as array in the query parameter. When I pass as given below, I am getting error.

{"code":2,"message":"data_services must be an array and not empty"}

Please let me know, how can I pass an array as query parameter in Postman.

Can you post the DELETE method signature/ code? – Waldenses

Sorry. I was wrong. I misread the DELETE method. It was expecting array in the content section. I have provided answer for clarity – Chaconne

Answer 1

I mis-read the DELETE method. It was expecting array of databases in the body of the Http body section, instead of on query parameter section. I provided the array as given below and it got succeeded.

The below is the way, I passed array to Http request in the body section.

Answer 2

You need to create 2 keys with the same name and add postfix []

Answer 3

You can specify the parameter key multiple times with different values.
Don't use square brackets or numbers like an array in code.

This will result in a query string like so:

?data_services=somename&data_services=anothername

no. it is not working out. Even if a specify a single value data_services=DBName, it is throwing same error – Chaconne

I have already tried it. Not working. mine is just list of databasename and not associative array. – Chaconne

Answer 5

I learned today that you can also pass in a GET param as

some_end_point?param1=123456&data_services[0].param2:123456&data_services[0].param3:123456
