question

Do you have Rest Pay Display installed and open on the Clover device? If so, I am not sure what you are doing wrong, but Clover has some very comprehensive documentation on the Rest Pay API, including how to obtain a token, etc. https://docs.clover.com/docs/rest-pay-overview. You shouldn't be using a merchant token.

how to install "Rest Pay Dispaly", from bleow ?

https://sandbox.dev.clover.com/developers/dev-apks

just need install "REST Pay Display"? or more then one apk need be installed?

I want my pos can connect clover flex to call payment, POS software an clover device both in my store. now my device show

this is my first contact with clover. Although I read the documentation, I know that there are local API and cloud API, but I still don't understand how to implement it. It would be great if you could explain it clearly.

You can't use "Secure Network Pay Display" (screenshot provided). You need to install "Rest Pay Display", you can do that from your device (more tools option, I believe) or from your dashboard. Then you need to read the docs, I would start here - https://docs.clover.com/docs/rest-pay-development-basics.

yes, after I install "Rest Pay Display" from more tools option, http request can be accepted,

I see the docs says, api need oauth token, which need app's id and secret, but "Rest Pay Display" is not my app, how can i get the access token?

PS: I try the "API tokens" from "Business Operations" , it response 401

please explain more, I can't pay

octordle

ok, this is my step

1，I create a api token from merchanr dashboard "Account & setup" - "Bussiness operations" - "API Tokens"(doc say use oauth, but i cannot use "Rest Pay Dispay", so i try the api token)

2, my device ip is 192.168.1.5 and device id is C143UQ20340091

3, I use

curl ^
--url http://192.168.1.5:12346/connect/v1/device/status ^
--header "X-Clover-Device-Id: C143UQ20340091" ^
--header "X-POS-Id: THAI BOWL" ^
--header "accept: application/json" ^
--header "authorization: Bearer {API_TOKEN}"

it response 401 unauthorization

could you help to tell me how to find header authorization

You can't use a merchant token (token created from the merchant's dashboard). You need to create an app and then obtain a token via the OAuth flow. The link I previously sent you describes the steps necessary to do this:

https://docs.clover.com/docs/rest-pay-development-basics

You need to invest the time to read the docs and learn how to use the API.

I can create a app and publish, then I do the oauth flow and get a access_token with my appid + secret, then the access_token can use to connect "Rest Pay Display"?

it mean even if my app is not associated with rest pay dispaly, I can use its access_token to communicate with rest pay

That is correct. The app you create represents the integration and will be installed by the merchant and used to obtain an access token (via the OAuth flow) which will be used to authenticate your calls to Rest Pay Display. See the first two FAQs in the documentation - https://docs.clover.com/docs/faqs#rest-pay-display.

thank you, I will try

a more question, if I use "Cloud Pay Display", I need install Cloud Pay Display, and the oauth flow is the same as "Rest Pay Display"?
