API load test using OAuth2.0 authentication

[Jignesh Mithapara]

Hello,

We have few APIs which are secured with OAuth2.0 security. We are using postman to generate token using OAuth 2.0. We generate token using "Access Token URL", "Client ID", "Client Secret" and "Grant Type=Client Credentials" in the postman and use this token into API.

Now, we want to perform load test for these APIs using apache JMeter 3.1. For that, we need to generate token with different users and we need to use these tokens in the APIs.

I searched on web but I didn't found any proper solution. we have OAuth sampler but it is using OAuth1.0.

So, can somebody tell me how can I perform load test using OAuth2.0 authentication in JMeter ?

Thanks in advance..

Hi Jignesh Mithapara ,

Thanks for the solution and it worked for me .

I used Thread group 2 and got the API Response.

I liked to know what is the thread group 1 ?

Thanks

[Jignesh Mithapara]

Thanks.

oauth2 has token to access any api. so we want to exract token from the response. Thread group 1 is used to exract this token from the response. This token will expire in 30-45 mins so we don't want to generate token every time. so we send this token to thread group 2 for accessing API...

Let me know if you have still any doubt..

Regards,
Jignesh

I use Postman to generate a token and use this in my Jmeter.

So do you use Threadgroup1 to generate a tocken instead of postman ?

I am very new to Jmeter , so bit confused on this concept.

[Jignesh Mithapara]

This code works with jmeter as you work with postman. This code definitly works.. Try it and let me know..

HI Jagnesh,

Can you please let me know how we need to do OAUTH(1.0) API testing with Jmeter.

I stuck in the same from last 1 week.

Regards,

Sanjay

Hi,

If your application is using oauth1.0 then you can use oauth sampler.

Hi Sanjay,

You can download this oauth sampler from https://jmeter-plugins.org/wiki/OAuthSampler/ site. 

It also describe you usecase of this sampler.

[Sanjay Sharma]

I am using Jmeter 3.2 , I don't think oauth sampler is for this version.

I have 4 values 

consumer key, consumer secret and token and token secret.

In OAUTH sampler we have provision to add only two values related with consume where I will add token values.

Sanjay

Hi Sanjay,

You can use OAuth1.0 sampler for your test. You just need to add consumer key, consumer secret and other necessary information in the sampler. You can't add manual token in any sampler due to session issue and Token will generate automatically. This token will use directly in your API. 

Thanks,

Jignesh Mithapara
