Merge Go Library

The Merge Go library provides convenient access to the Merge API from Go.

Requirements

This module requires Go version >= 1.19.

Installation

Run the following command to use the Merge Go library in your Go module:

go get github.com/merge-api/merge-go-client

Instantiation

import (
  "context"
  "fmt"

  merge "github.com/merge-api/merge-go-client"
  mergeclient "github.com/merge-api/merge-go-client/client"
)

client := mergeclient.NewClient(
  mergeclient.ClientWithAuthApiKey("<YOUR_API_KEY>"),
  mergeclient.ClientWithHeaderAccountToken("<YOUR_ACCOUNT_TOKEN>"),
)

Categories

This SDK contains the ATS, HRIS, CRM, Ticketing, Accounting, and File Storage categories. Even if you do not plan on using more than one Merge API category right now, the SDK provides upgrade-flexibility in case you find new Merge API categories useful in the future.

Each category is namespaced:

client := mergeclient.NewClient(
  mergeclient.ClientWithAuthApiKey("<YOUR_API_KEY>"),
  mergeclient.ClientWithHeaderAccountToken("<YOUR_ACCOUNT_TOKEN>"),
)

client.Ats(). # APIs specific to the ATS Category

client.Hris(). # APIs specific to the HRIS Category

Categories

This SDK contains both the ATS, HRIS, CRM, Ticketing, and Accounting categories. Even if you do not plan on using more than one Merge API category right now, the SDK provides upgrade-flexibility in case you find new Merge API categories useful in the future.

Each category is namespaced:

client := mergeclient.NewClient(
  mergeclient.ClientWithAuthApiKey("<YOUR_API_KEY>"),
  mergeclient.ClientWithHeaderAccountToken("<YOUR_ACCOUNT_TOKEN>"),
)

client.Ats(). // APIs specific to the ATS category

client.Hris(). // APIs specific to the HRIS category

Usage

Create Link Token

import (
  "context"
  "fmt"

  merge "github.com/fern-api/merge-go"
  mergeclient "github.com/fern-api/merge-go/client"
  "github.com/fern-api/merge-go/ats"
)

client := mergeclient.NewClient(
  mergeclient.ClientWithAuthApiKey("<YOUR_API_KEY>"),
  mergeclient.ClientWithHeaderAccountToken("<YOUR_ACCOUNT_TOKEN>"),
)
linkTokenResponse, err := client.Ats().LinkToken().Create(
  context.TODO(),
  &ats.EndUserDetailsRequest{
    EndUserEmailAddress:     "[email protected]",
    EndUserOrganizationName: "acme",
    EndUserOriginId:         "1234",
    Categories:              []ats.CategoriesEnum{ats.CategoriesEnumAts},
    LinkExpiryMins:          merge.Int(30),
  },
)
if err != nil {
  return err
}
fmt.Printf("Created link token %s\n", linkTokenResponse.LinkToken)

  merge "github.com/fern-api/merge-go"
  mergeclient "github.com/fern-api/merge-go/client"

)
candidateList, err := client.Ats().Candidates().List(

  &ats.CandidatesListRequest{
    CreatedBefore: merge.Time(time.Now()),
  },
)
if err != nil {
  return err
}
fmt.Printf("Retrieved %d candidates\n", len(candidateList.Results))

Create Ticket

import (
  "context"
  "fmt"
  "time"

  merge "github.com/fern-api/merge-go"
  mergeclient "github.com/fern-api/merge-go/client"
  "github.com/fern-api/merge-go/ticketing"
)

client := mergeclient.NewClient(
  mergeclient.ClientWithAuthApiKey("<YOUR_API_KEY>"),
  mergeclient.ClientWithHeaderAccountToken("<YOUR_ACCOUNT_TOKEN>"),
)
ticketResponse, err := client.Ticketing().Tickets().Create(
  context.TODO(),
  &ticketing.TicketEndpointRequest{
    Model: &ticketing.TicketRequest{
      Name: merge.String("Please add more integrations"),
      Assignees: []string{
        "17a54124-287f-494d-965e-3c5b330c9a68",
      },
      Creator: merge.String("3fa85f64-5717-4562-b3fc-2c963f66afa6"),
      DueDate: merge.Time(time.Now().Add(24 * time.Hour)),
      Status:  ticketing.NewTicketRequestStatusFromTicketStatusEnum(ticketing.TicketStatusEnumOpen),
    },
  },
)
if err != nil {
  return err
}
fmt.Printf("Successfully created ticket with ID %q\n", *ticketResponse.Model.Id)

Timeouts

Setting a timeout for each individual request is as simple as using the standard context library. Setting a one second timeout for an individual API call looks like the following:

ctx, cancel := context.WithTimeout(context.TODO(), time.Second)
defer cancel()
employeeList, err := client.Hris().Employees().List(
  ctx,
  &hris.EmployeesListRequest{
    CreatedBefore: merge.Time(time.Now()),
  },
)
if err != nil {
  return err
}

Client Options

A variety of client options are included to adapt the behavior of the library, which includes configuring authorization tokens to be sent on every request, or providing your own instrumented *http.Client. Both of these options are shown below:

client := mergeclient.NewClient(
  mergeclient.ClientWithAuthApiKey("<YOUR_API_KEY>"),
  mergeclient.ClientWithHTTPClient(
    &http.Client{
      Timeout: 5 * time.Second,
    },
  ),
)

Providing your own *http.Client is recommended. Otherwise, the http.DefaultClient will be used, and your client will wait indefinitely for a response (unless the per-request, context-based timeout is used).

Errors

Structured error types are returned from API calls that return non-success status codes. For example, you can check if the error was due to a bad request (i.e. status code 400) with the following:

employeeList, err := client.Hris().Employees().List(
  context.TODO(),
  &hris.EmployeesListRequest{
    CreatedBefore: merge.Time(time.Now()),
  },
)
if err != nil {
  if apiErr, ok := err.(*core.APIError); ok && apiErr.StatusCode == http.StatusBadRequest {
    // Do something with the bad request ...
  }
  return err
}

These errors are also compatible with the errors.Is and errors.As APIs, so you can access the error like so:

employeeList, err := client.Hris().Employees().List(
  context.TODO(),
  &hris.EmployeesListRequest{
    CreatedBefore: merge.Time(time.Now()),
  },
)
if err != nil {
  var apiErr *core.APIError
  if errors.As(err, apiError); ok {
    switch apiErr.StatusCode {
      case http.StatusBadRequest:
        // Do something with the bad request ...
    }
  }
  return err
}

If you'd like to wrap the errors with additional information and still retain the ability to access the type with errors.Is and errors.As, you can use the %w directive:

employeeList, err := client.Hris().Employees().List(
  context.TODO(),
  &hris.EmployeesListRequest{
    CreatedBefore: merge.Time(time.Now()),
  },
)
if err != nil {
  return fmt.Errorf("failed to list employees: %w", err)
}

Contributing

While we value open-source contributions to this SDK, this library is generated programmatically. Additions made directly to this library would have to be moved over to our generation code, otherwise they would be overwritten upon the next generated release. Feel free to open a PR as a proof of concept, but know that we will not be able to merge it as-is. We suggest opening an issue first to discuss with us!

On the other hand, contributions to the README are always very welcome!
