In the Pre-request script, is it possible to add a Bearer Style authentication in the pm.sendRequest function? If so, what does the syntax look like? ``` pm.sendRequest({ url: "URL of some type", method: 'POST', auth: { type:'bearer', token: 'Bearer Token' } header: { 'Content-Type': 'application/xml' }, body: { mode: 'raw', raw: `Body Data of some type` } }, function (err, res) { if(err) { throw new Error(err); } else { console.log("auth was successful") } }); ``` ---

You add a number of different things into `.sendRequest()`. I’m not sure of the full context of the actual request your making but there are some different examples in this gist which I always find useful. > ---

It’s a pre-request script that requires Bearer Token authorization for the requests in it. I already have the token, I just need to pass it into a request like what I listed as an example. I already know how to do a basic auth with similar syntax. My issue is around what the syntax for a bearer style authentication. ``` // Authentication pm.sendRequest({ url: 'https://test.com', method: 'POST', auth: { type: "basic", basic: [ {key: "username", value:"user"}, {key: "password", value:"password"} ] }, body: { mode: 'urlencoded', urlencoded: [ {key: "Content-Type", value: "application/x-www-form-urlencoded", disabled: false}, {key: "grant_type", value: "client_credentials", disabled: false} ] } }, function (err, res) { if(err) { throw new Error("An error occurred during authentication, please review:\n" + JSON.stringify(err)); } else { console.log(res.json()); // Confirm the request was successful pm.expect(res).to.have.property('code', 200); let data = res.json(); pm.environment.set("token", "Bearer " + data.access_token); } }); ``` ---

My mistake, I thought you were trying to _get_ one with that request 🤦‍♂️ It looks like you already added the word `Bearer` when setting the variable so you would just need to add a new `Authorization` header with the value in the example. ```auto pm.sendRequest({ url: "URL of some type", method: 'POST', header: { 'Authorization': `${pm.environment.get('token')}`, 'Content-Type': 'application/json' }, body: { mode: 'raw', raw: `Body Data of some type` } }, function (err, res) { if (err) { throw new Error(err); } else { console.log("auth was successful") } }); ``` More information on Javascript template literals: [https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template\_literals](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals) ---

I attempted this with my request and it’s still failing validation. It requires that I have the Bearer Authorization setup separately. ---

I would have thought that if you have the pre-request script that’s getting the Bearer Token, wouldn’t you just use that token value in an Authorization Header of your normal requests. I don’t really understand why you’re using this in another pre-request. I don’t know your context and what you have in front of you so that only think that I can offer is a ‘guess’. ---

It’s due to some constraints that are being set from the BE due to code note present in the FE of the project. I believe once those constraints are removed, your solution should work with no issue ---

I found out how to do this type of auth in the pre-request script: ``` pm.sendRequest({ url: "some URL", method: 'POST', auth: { type: "bearer", bearer: [ { key: "token", value: "Bearer " + bearerToken, type: "string" } ] }, header: { 'Content-Type': 'application/xml' }, body: { mode: 'raw', raw: `type of body` } }, function (err, res) { if(err) { throw new Error(err); } else { console.log("auth was successful") } }); ``` ---

Ha, I actually had it this way (minus the type property) in one of my initial responses but I edited the code after seeing your example 🤦‍♂️ Totally up to you and down to personal preference but I’m a fan of this syntax. ```auto `Bearer ${bearerToken}` ``` To me, it feels more readable than: ```auto "Bearer " + bearerToken ``` ---

@Zachary: Great post! It helped me to solve my problem. However, when I first tried this I had an issue with the token. Analysis of the ressonse headers revealed that the Bearer token was like this: ‘Bearer Bearer llkjh876976jjhgjhg874653hgIj…’ The word ‘Bearer’ was used twice, hence the authentication was KO. So I deleted the “Bearer” part of the ‘value:’ assignment bearer: [ { key: “token”, value: bearerToken, type: “string” } ] and it did work immediately for me. Thanks ---

God blessed you with this response, after 2 hours of solving the problem its finally over thanks to your help. God blessed, alhamdulillah
