Question

Passing an array object as HTTPCaller query string

M

I am trying to access a JSON API by using a HTTPCaller and I am struggling with passing an array object as a Query String Parameter. The documentation for the 'extra' key I am trying to access looks like this.

 

Request Query parametersThe code sample they give where you can see the 'extra' parameter as an array is here:

{

"key": "xxxxx-xxxxx-xxxxx-xxxxx",

"query": "High Street",

"country": "gbr",

"id": "town=Maidenhead",

"extra": {

"exclude_areas": [

"gbr_channel_islands",

"gbr_northern_ireland",

"usa_non_contiguous"

],

"exclude_pobox": true,

"best_match_only": true,

"no_groupings": true

}

}

 

How do I go about adding the extra array as a query string parameter when the API is expecting to be given an array?

 

many thanks in advance

You'll have to URL encode the JSON document before the HTTPCaller using the TextEncoder, e.g.:

Thanks David - I am missing a step I think.

if I pass the text I think I need to the Textencoder ie

{

   "best_match_only": true,

}

the encoded output is %7B%0A%09%22best_match_only%22%3A%20true%2C%0A%7 which the HTTPCaller still interprets as a string - what have a missed?

That is correct. Query parameters are always sent as strings, although the server may interpret it as something else once the string data arrives.

I think it might be an issue I can't overcome, as the API always seems to interpret what it is passed as a string. Thank you for your help though
