This is My code —

@amirmanji please help me

Developing OAuth authentication / signing from scratch can be tricky and lead to errors, have you considered using a library like https://github.com/linvi/tweetinvi to handle this part?

You can also compare the headers that ‘twurl’ outputs and try to see if you are missing something that is necessary.

Hi @JBabichJapan,

Now it is working but if i am passing one values inside querry parameter strings like -

https://ads-api.twitter.com/3/stats/accounts/18ce54om822?end_time=2018-11-19&entity=ACCOUNT&entity_ids=avc3z,avo2i,avqlt,aww2n&granularity=TOTAL&metric_groups=BILLING,ENGAGEMENT&placement=ALL_ON_TWITTER&start_time=2018-11-14

it is showing error but when i am pass one parameters like -

https://ads-api.twitter.com/3/stats/accounts/18ce54om822?end_time=2018-11-19&entity=ACCOUNT&entity_ids=avc3z&granularity=TOTAL&metric_groups=ENGAGEMENT&placement=ALL_ON_TWITTER&start_time=2018-11-14

then it is working

it is resolved. Actually, I think encoding is not correct that’s way the problem comming
i can do my working but if you tell me how to encode prperly that would be good.

Thanx
