After you submit the task to us, you should receive in the response a 'Task id' if it's successfull. Please read errorCode: full list of errors if you didn't receive the task id.

Example Response

json
{
    "errorId": 0,
    "errorCode": "",
    "errorDescription": "",
    "taskId": "61138bb6-19fb-11ec-a9c8-0242ac110006" 
}

Getting Results

After you have the taskId, you need to submit the taskId to retrieve the solution. Response structure is explained in getTaskResult.

go
package main

)

func main() {
	// first you need to install sdk
	//go get github.com/capsolver/capsolver-go
	//export CAPSOLVER_API_KEY='...' or
	//capSolver := CapSolver{ApiKey:"..."}

	capSolver := capsolver_go.CapSolver{}
