This endpoint supports intelligent deduplication and returns separate arrays for newly created and existing accounts.

Important: This endpoint creates new accounts but does NOT update existing ones. Existing accounts that match the criteria will be returned in the existing_accounts array without modification.

To update existing accounts, use the Bulk Update Accounts endpoint. - [Bulk Update Accounts](https://docs.apollo.io/reference/bulk-update-accounts.md): Use the Bulk Update Accounts endpoint to simultaneously update multiple accounts in your team's Apollo account.

This endpoint allows you to update common fields across multiple accounts efficiently, such as account stages, owners, names, and custom fields.

You can update up to 1000 accounts per request.

Important: Asynchronous processing (async parameter) is only supported when using account_ids to apply the same updates to all accounts. If you attempt to use async with account_attributes (individual updates per account), the request will fail with a 422 error. - [Create an Account](https://docs.apollo.io/reference/create-an-account.md): Use the Create an Account endpoint to add a new account to your team's Apollo account.

In Apollo terminology, an account is a company that your team has explicitly added to your database.

Apollo does not apply deduplication processes when you create a new account via the API.

To protect Apollo's performance for all users, this endpoint has a display limit of 50,000 records (100 records per page, up to 500 pages). Add more filters to narrow your search results as much as possible. This limitation does not restrict your access to Apollo's database; you just need to access the data in batches. - [Update Account Owner for Multiple Accounts](https://docs.apollo.io/reference/update-account-ownership.md): Use the Update Account Owner for Multiple Accounts endpoint to assign multiple accounts to a different user in your team's Apollo account.

To update more than the account owner, such as domains or phone numbers, use the Update an Account endpoint instead.

This endpoint supports intelligent deduplication and returns separated arrays for newly created and existing contacts.

Important: This endpoint creates new contacts but does NOT update existing ones (except for placeholder contacts from email imports). Existing contacts that match the criteria will be returned in the existing_contacts array without modification.

To update existing contacts, use the Bulk Update Contacts endpoint. - [Bulk Update Contacts](https://docs.apollo.io/reference/bulk-update-contacts.md): Use the Bulk Update Contacts endpoint to update multiple contacts in your team's Apollo account simultaneously.

This endpoint allows you to update common fields across multiple contacts efficiently, such as contact stages, owners, custom fields, and other contact attributes.

In Apollo terminology, a contact is a person that your team has explicitly added to your database. A contact will have their data enriched in some way, such as accessing an email address or a phone number.

By default, Apollo does not apply deduplication processes when you create a new contact via the API. If your entry has the same name, email address, or other details as an existing contact, Apollo will create a new contact instead of updating the existing contact.

To enrich data for only 1 company, use the Organization Enrichment endpoint instead.

Enriched data potentially includes industry information, revenue, employee counts, funding round details, and corporate phone numbers and locations.

This endpoint's rate limit is throttled to 50% of the Organization Enrichment endpoint's per-minute rate limit, and is 100% of the hourly and daily rate limits for the same individual endpoint. - [Bulk People Enrichment](https://docs.apollo.io/reference/bulk-people-enrichment.md): Use the Bulk People Enrichment endpoint to enrich data for up to 10 people with a single API call. To enrich data for only 1 person, use the People Enrichment endpoint instead.

Apollo relies on the information you pass via the endpoint's parameters to identify the correct people to enrich. When you provide more information, Apollo is more likely to find matches within its database. If you only provide general information, such as a name without a domain or email address, you might receive a `200` response, but the response will indicate that no records have been enriched. The details for each person should be passed as an object with the `details[]` array.

By default, this endpoint does not return personal emails or phone numbers. Use the `reveal_personal_emails` and `reveal_phone_number` parameters to retrieve emails and phone numbers. If you set either of these parameters to `true`, Apollo will attempt to provide emails or phone numbers for all matches.

You can use also use the `run_waterfall_email` and `run_waterfall_phone` parameters to run waterfall enrichment via this endpoint. [Waterfall enrichment](https://knowledge.apollo.io/hc/en-us/articles/34071089002509-Waterfall-Enrichment-Overview) gives you broader data coverage by checking connected third-party data sources for contact emails and phone numbers. When you call this endpoint and include at least one waterfall parameter, Apollo returns an immediate synchronous response with demographic and firmographic data, along with a waterfall enrichment request status. Apollo delivers enriched emails and/or phone numbers asynchronously to a configured webhook.

**Webhook Requirements:** - **HTTPS Required:** Your endpoint must be publicly accessible over HTTPS. - **Rate Limiting:** Ensure your webhook endpoint can handle the volume of webhook traffic sent by Apollo. - **Idempotency:** Apollo may retry webhook calls. Your endpoint should be idempotent to handle duplicate payloads safely. Using this endpoint will consume credits based on your account's pricing plan. If you run waterfall enrichment parameters, your [credit usage](https://knowledge.apollo.io/hc/en-us/articles/34071089002509-Waterfall-Enrichment-Overview#does-waterfall-enrichment-require-credits) depends on the type of data you request (emails and/or phone numbers) and which data source returns enriched data. To view a summary of Apollo's pricing, visit the public pricing page ↗ For detailed information regarding API credit usage, see the API enrichment ↗ section on the *About Credits* page (login required).

This endpoint's rate limit is throttled to 50% of the People Enrichment endpoint's per-minute rate limit, and is 100% of the hourly and daily rate limits for the same individual endpoint. - [Organization Enrichment](https://docs.apollo.io/reference/organization-enrichment.md): Use the Oganization Enrichment endpoint to enrich data for 1 company. To enrich data for up to 10 companies with a single API call, use the Bulk Organization Enrichment endpoint instead.

To enrich data for up to 10 people with a single API call, use the Bulk People Enrichment endpoint instead.

Apollo relies on the information you pass via the endpoint's parameters to identify the correct person to enrich. If you provide more information about a person, Apollo is more likely to find a match within its database. If you only provide general information, such as a name without a domain or email address, you might receive a 200 response, but the response will indicate that no records have been enriched.

By default, this endpoint does not return personal emails or phone numbers. Use the `reveal_personal_emails` and `reveal_phone_number` parameters to retrieve emails and phone numbers.
