facing issue in integrating third party API in endpoint

I am tryign to integrate a third-party API calls in my endpoint using oauth.

steps :-

1.  API call to get new access token.

I am getting below response >>  {"expires_in":1209600,"refresh_token":"AVm+qqHWICxNvhDcNSvtFRIyMw==","access_token":"AZoOjM6fLc5PhGUwjgd7zCoyMQ=="}

2. I want to get 'access_token' value from above response and to pass this value in header for 2nd API call.

 

observation : If I hardcode it into a freemaeker variable then its working fine

<#assign a_token = "ASfJllLBFpNPucOl7hMQptwyMQ==" />

<#assign http_response_client_lists = http.client.request("https://api.createsend.com/api/v3.1/clients.json").header("Authorization", "Bearer "+a_token).get()

 

issue : when I store access_token into a freemarker variable and try to use that var in 2nd API, its not working.

<#assign a_token = json_response.access_token />

 

<#assign http_response_client_lists = http.client.request("https://api.createsend.com/api/v3.1/clients.json").header("Authorization", "Bearer "+a_token).get()

 

Am I missing anything here?

Please help me find the solution.

 

Thanks,

Vaishnavi

    vaishnavi have you try to display the value of the 'a_token' variable to see its content?

     

    <#assign a_token = json_response.access_token />

    Or try:

     

    <#assign a_token = json_response.access_token?json_string  />

    When I print ${a_token} it print the correct string value but its not working in API header.

     

    I have tried j_string, js_string, json_string but nothing is working.

    I getting below error :

    error making http request: Unauthorized

     

    Is here any issue due to encoding of API response ?

     

    when I print ${a_token?url} for <#assign a_token = "ASfJllLBFpNPucOl7hMQptwyMQ==" /> 

    output is : ASfJllLBFpNPucOl7hMQptwyMQ%3D%3D

     

    and when I print ${a_token?url} for <#assign a_token = json_response.access_token />

    output is : ASfJllLBFpNPucOl7hMQptwyMQ%26%2361%3B%26%2361%3B

     

    means it takes HTML encoded access_token  as ASfJllLBFpNPucOl7hMQptwyMQ&#61;&#61;

    Note here : &#61; is HTML encoded equivalent of equal sign( = )

    and again encodes it to MQ%26%2361%3B%26%2361%3B

     

    Does anyone know how to decode HTML encoded string in freemarker variable?

    Hi vaishnavi

     

    I have encountered the behavior once and it is being investigated ( JakeS may be interested in this topic). In the meantime, to overcome these encoding issues in the past, I have used a workaround

     

    <#assign token = jsonResp.access_token?replace("&amp;", "&")?replace("&#61;", "=")?replace("&lt;","<")?replace("&gt;",">")?replace("&amp;quot;","\"") />

     

    This is, of course, just a workaround using string replace but it did the trick for me.

     

    Thanks

    PaoloT,

    Thanks for your suggestion.
