Good morning, First off - I just want to say that I am not a developer and have minimal developer knowledge. I’m trying to figure out why we are hitting the API call limit in HubSpot. Is there a way to see what integration is maxing out the call limit? Thank you in advance for your help. Best, Jake ---

Welcome, [@jakeravelo](https://community.hubspot.com/u/jakeravelo)! We can certainly look into this for you. What is your Hub ID? ---

Thanks, [@jakeravelo](https://community.hubspot.com/u/jakeravelo)! I’ll investigate further with my team. It’s important to note, though, that the 40,000 call limit mentioned [here](https://developers.hubspot.com/apps/api_guidelines) applies to requests authenticated using your account’s [API key](https://app.hubspot.com/integrations-settings/2154169/api-key) rather than the apps which are listed [here](https://app.hubspot.com/integrations-settings/2154169/installed). Do you or Mark (who created the key [here](https://app.hubspot.com/integrations-settings/2154169/api-key)) know of any custom processes using the key? ---

Hey [@Isaac\_Takushi](https://community.hubspot.com/u/isaac_takushi), I’m unaware of any custom processes currently using the key. ---

Hey, [@jakeravelo](https://community.hubspot.com/u/jakeravelo). We found that the majority of errors over the past week were `409`s from the contact creation endpoint. (At least 30K each day, up to 36K on Saturday.) It seems your system is attempting to pass an existing `email` values to the [Create a new contact](https://developers.hubspot.com/docs/methods/contacts/create_contact) endpoint. Unlike the [Create or update a contact](https://developers.hubspot.com/docs/methods/contacts/create_or_update) endpoint, the `/contacts/v1/contact` endpoint will _only_ attempt to _create_ new contacts, so passing existing email addresses will cause failures. The team also identified extraneous lookups. For example, these two calls occurred right after each other: ```auto 474 12/3/2018, 11:57:23 AM 204 POST /contacts/v1/contact/vid/201776251/profile 476 12/3/2018, 11:57:23 AM 200 GET /contacts/v1/contact/email/scsc.[lastname]@yahoo.com/profile ``` `scsc.[lastname]@yahoo.com` _is_ vid `201776251`, so you could save half of these types of calls by attempting to update with the [Create or update a contact](https://developers.hubspot.com/docs/methods/contacts/create_or_update) endpoint or, better yet, the [batch create or update](https://developers.hubspot.com/docs/methods/contacts/batch_create_or_update) endpoint. To reiterate, these calls _are_ using your account’s API key and are _not_ caused by any of [these integrations](https://app.hubspot.com/integrations-settings/2154169/installed). ---

Hey [@Isaac\_Takushi](https://community.hubspot.com/u/isaac_takushi), Thank you so much for the clarification! I will pass this information along. I hope you have a great day. ---

Hi Isaac - We’re having a similar problem. Can you verify Hubspot ID #4622020 for us? ---

Welcome, [@RobertWorkshop](https://community.hubspot.com/u/robertworkshop)! Could you describe your situation a bit more thoroughly? According to [this endpoint](https://developers.hubspot.com/docs/methods/check-daily-api-usage), account **4622020** has only used **9,929** out of 40,000 today, 4 December 2018, so I’m not sure which limit you’re hitting.
