How to establish API connection between HubSpot and SQL Server database

I’m stuck trying to sync customer information between HubSpot and my SQL Server database. The goal is to keep both systems updated with the same user data from my web application.

What I’ve tried so far

I tested the HubSpot API using Google’s OAuth testing tool and it worked fine. Now I need to build the same functionality in R but I’m having authentication problems.

Option 1: Third-party service
Found a service called Zapier but haven’t used them before and would prefer to build this myself.

Option 2: R packages
Tried using ROAuth and httr but can’t get past the authentication step. Here’s my attempt:

endpointURL <- 'https://api.hubapi.com/contacts/v1/lists/all/contacts/all'
authEndpoint <- 'https://app.hubspot.com/oauth/authorize?client_id=[app_id]&scope=contacts%20automation&redirect_uri=https://[mydomain]'
clientID <- 'my_application_client_id'
clientSecret <- 'my_application_secret'

auth_config <- OAuthFactory(consumerKey=clientID,
                           consumerSecret=clientSecret,
                           requestURL=endpointURL,
                           accessURL="???",
                           authURL=authEndpoint)

Also attempted this simpler approach:

curl('https://api.hubapi.com/contacts/v1/lists/all/contacts/all/hapikey=[api_key]/get')

Available credentials:

  • Client ID and Secret
  • API key
  • App ID

Any ideas on what I’m missing with the authentication process?

Skip OAuth and go with a private app - much simpler. Head to HubSpot settings > integrations > private apps, create one with contacts read/write permissions. You’ll get an access token that doesn’t expire. Then just use httr with bearer auth: GET(url, add_headers(Authorization = paste("Bearer", token)))

Skip OAuth for now - get a basic connection working first. Your API key approach is on the right track, just fix the syntax:

api_key <- "your_api_key_here"
url <- paste0("https://api.hubapi.com/contacts/v1/lists/all/contacts/all?hapikey=", api_key)
response <- GET(url)

I hit the same issues connecting our CRM to an internal database. API keys are way simpler for testing and work fine for most cases. Get data flowing first, then switch to OAuth if you need it. For SQL Server, use RODBC or odbc package for database connections. Don’t forget to enable the right scopes in your HubSpot app developer settings - that tripped me up too.

Yes, dealing with HubSpot’s OAuth can be quite challenging. I encountered similar difficulties in my projects as well. ROAuth tends to be incompatible with HubSpot because it uses OAuth 2.0 rather than 1.0. I recommend using the httr package with oauth2.0_token for better compatibility. Ensure that your access token URL points to https://api.hubapi.com/oauth/v1/token. It’s crucial to verify that your redirect URI precisely matches what’s configured in your HubSpot app settings—any discrepancies can lead to failures in authentication. Regarding SQL Server connections, I suggest using DBI along with the odbc driver instead of RODBC, as it offers enhanced connection pooling that’s beneficial for regular syncing. Finally, take the time to debug each component of your setup individually; this approach can simplify the troubleshooting process significantly.

Been there - syncing data between multiple systems is a nightmare. Building OAuth flows in R sucks and maintaining API connections gets messy real quick.

Skip the authentication headaches and custom sync logic. Just automate it. Set up a workflow that watches HubSpot for changes, transforms the data, and pushes it to SQL Server. Works both ways.

You don’t deal with OAuth tokens, refresh cycles, or error handling. Configure the HubSpot trigger, add SQL Server credentials, map your fields. Takes 30 minutes instead of days debugging R code.

I use this for all our CRM integrations now. Way more reliable than custom scripts and handles rate limits and retries automatically. You get monitoring and logs without building them.
