Trying to send access token from loopback to third party api - json

Question

I have my API in loopback 3.x. First I created an empty project and right after that I ran npm install loopback-connector-rest --save and lb datasource in the console to have a link to an external API called Userlike. It this URL https://www.userlike.com/api/external/message/chat_meta/.
Then I created a model with no parameters called Messages.
I had no problems executing as I used node . and there was no error, and in localhost:3000 I could visualize my API.
But I had a problem when I clicked GET in the page a 401 error because to access the API in Userlike I needed to send my token so I could get the data, so I modified the datasources.json file and I had this:
{
"userlikeRESTdatasource": {
"name": "userlikeRESTdatasource",
"baseURL": "https://www.userlike.com/api/external/message/chat_meta/",
"crud": false,
"connector": "rest",
"operations": [
{
"functions": {
"getMessages": []
},
"template": {
"method": "GET",
"url": "https://www.userlike.com/api/external/message/chat_meta/",
"headers": {
"accepts": "application/json",
"content-type": "application/json",
"authorization": "8c149a3d-4acf-362e-880c-30ec2f5ecaf"
},
"responsePath": "$.results.*"
}
}
]
}
}
The authorization field I put in the header didn't work as I still received
{
"error": {
"statusCode": 401,
"name": "Error",
"message": "Authorization Required",
"stack": "Error: Authorization Required\n
}
}
My idea was to do something like:
headers.append('Authorization', '8c149a3d-4acf-362e-880c-30ec2f5ecaf7');
headers.append('Access-Control-Allow-Origin', '*');
headers.append('Access-Control-Allow-Methods', 'POST, GET, OPTIONS');
headers.append('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Authorization, Accept');
But with loopback. So I could receive the data from the Userlike API and next I could modify or just use the data I wanted.
But I still can't figure out how can I modify my datasources.json or if I need to create something in another file to make it possible to send the token as the authorization to that URL I'm using.

Answer 1

Pass access token with HTTP header by using this
headers.append('X-Access-Token', '8c149a3d-4acf-362e-880c-30ec2f5ecaf7');
or also pass this token as a parameter.
?access_token=8c149a3d-4acf-362e-880c-30ec2f5ecaf7
This will help.
