Custom connector with two step authentication

Giorda62 — Fri, 17 Oct 2025 10:24:54 GMT

Hello,

I'm pretty new to workato and not quite familiar with Ruby.

I need to write a custom connector that authenticates using a POST request passing username/password and receives back an auth token; the Token will then be used in the header of following requests; I'm struggling in identifying the correct form to write the "authorization" block of the "connection" section; I've tried using the following:

"connection": {

"fields": [

{

"name": "username",

"label": "Username",

"hint": "Enter HDA username for authentication.",

"optional": false

{

"name": "password",

"label": "Password",

"control_type": 'password',

"hint": "Enter your password for authentication.",

"optional": false

{

"name": "BaseURL",

"label": "Base URL",

"control_type": 'URL',

"hint": "Enter base URL for HDA integration.",

"optional": false

}

"authorization": {

"type": "custom_auth",

"acquire": {

"code": {

"post": {

"url": "https://XXXXXXXXXXX/api/login",

"headers": {

"Content-Type": "application/json"

"payload": {

"username": "::username::",

"password": "::password::"

"response_format": "json"

"response_mapping": {

"token": "token"

}

"base_uri": "https://XXXXXXXXXXX/api",

"apply": {

"headers": {

"Authorization": "::token::"

}

test: lambda do |_connection|

get("::BaseURL::")

end,

But I get the following error: Expected lambda for 'acquire' in hooks but got hash.

Any hint or suggestion?

Thanks a lot,

Giordano

Hii @Giorda62 ,
There are a few syntax issues in your code. I’ve adjusted the acquire block below

authorization: { type: 'custom_auth', acquire: lambda do |connection| response = post("https://XXXXXXXXXXX/api/login"). headers('Content-Type': 'application/json'). payload( username: connection['username'], password: connection['password'] ).request_format_json { token: response['token'] } end, refresh_on: [401, 403], apply: lambda do |connection| headers(Authorization: "Bearer #{connection['token']}") end }, base_uri: lambda do |connection| 'https://XXXXXXXXXXX/api' end }, test: lambda do |connection| get("#{connection['BaseURL']}") end

I hope this works :).
