summary: Programmatic access to Apollo's sales intelligence and engagement platform — data enrichment,
prospect and company search, and go-to-market workflow management.
description: 'The Apollo API provides programmatic access to [Apollo](https://www.apollo.io/), the all-in-one
sales intelligence and engagement platform. Use it to enrich people and company data (individually
or in bulk), search Apollo''s database of over 240 million contacts and 30 million companies, and
manage accounts, contacts, deals, sequences, tasks, calls, and conversations in your go-to-market
workflows.
## Base URL
All API requests are made to `https://api.apollo.io/api/v1`.
## Authentication
- **Apollo users** authenticate with an API key passed in the `x-api-key` request header. See [Create
API Keys](https://docs.apollo.io/docs/create-api-key).
- **Apollo partners** building integrations on behalf of mutual users authenticate with the [OAuth
2.0 authorization flow](https://docs.apollo.io/docs/use-oauth-20-authorization-flow-to-access-apollo-user-information-partners).
## Rate limits & credits
Rate limits and credit consumption depend on your [Apollo pricing plan](https://docs.apollo.io/docs/api-pricing).
Check your current limits and usage with the [View API Usage Stats and Rate Limits](https://docs.apollo.io/reference/view-api-usage-stats)
endpoint. For more details, see [Rate Limits](https://docs.apollo.io/reference/rate-limits) and the
[API FAQs](https://docs.apollo.io/docs/apollo-api-faqs).

**API key access:** `api/v1/emailer_messages/create` or `Master API key`

Use the Create an Email Draft endpoint to create a single, unsent email message (an email draft)
for a contact. The draft is created with a `drafted` status — this endpoint doesn''t send the
email.
To send the draft after creating it, call the Send
Email Now endpoint with the `id` returned in the response.
You must provide a `contact_id`
so Apollo knows who the email is for. Alternatively, to draft a reply within an existing email
thread, provide `in_response_to_emailer_message_id` instead and Apollo infers the contact and
recipients from the parent message.
The email is drafted from the user that owns the API
key. That user must have permission to email the contact (like by owning the contact or its account),
and the contact must not be blocked by any do not contact settings.
This endpoint returns
the created `emailer_message` object. If the draft is linked to an outreach task, a `task` object
is also returned.'

description: '## Endpoint essentials
**API key access:** `api/v1/emailer_messages/send_now` or `Master API key`
**OAuth scopes:** `emailer_messages_send_now`
**Credit usage:** `0 credits` — [Learn more about API pricing and credits](https://docs.apollo.io/docs/api-pricing).
Use the Send Email Now endpoint to immediately send an existing email message.This works for emails
that are currently in a `drafted`, `scheduled`, or `failed` state. Apollo schedules the email
to be sent right away and processes it asynchronously.
To first create an email draft,
use the Create an Email Draft
endpoint and pass the returned `id` to this endpoint.
The email is sent from the user
that owns the API key. That user must have a linked email account on the message, must have permission
to send from that email account, and must have permission to email the contact. The contact must
also not be blocked by any do not contact settings, and the user must not have exceeded their
daily email sending limit.
Because sending is processed asynchronously, a successful `200`
response means the email has been queued for sending — not that it''s been delivered. To check
whether the email was delivered, poll the Check
Email Send Status endpoint using the message `id`.
This endpoint returns the `emailer_message`
object. If the message is linked to an outreach task, a `task` object is also returned.'

**API key access:** `api/v1/emailer_messages/get_content` or `Master API key`
**OAuth scopes:** `emailer_messages_get_content`
**Credit usage:** `0 credits` — [Learn more about API pricing and credits](https://docs.apollo.io/docs/api-pricing).
Use the Get Email Content endpoint to retrieve the subject line, body, and recipients of emails
that your team has already sent. Provide up to 10 email message IDs in a single request, and choose
whether each body is returned as plain text or as the original HTML.
This endpoint only
returns emails that your team sent and that Apollo has finished sending. Drafted, scheduled, and
failed emails are never returned, and neither are replies or other inbound emails.
Any
ID that doesn''t match one of your team''s sent emails is left out of the response instead of
causing an error. This applies to unknown IDs, malformed IDs, IDs that belong to another team,
and IDs for emails that aren''t sent outreach emails. Because of this, always match the results
back to your request using the `id` field, and treat a missing `id` as "no sent email available"
rather than a failure.
To find email message IDs, call the Search
for Outreach Emails endpoint and identify the `id` value for each email.'

summary: Check Email Send Status
description: '## Endpoint essentials
**API key access:** `api/v1/emailer_messages/email_send_status` or `Master API key`
**OAuth scopes:** `emailer_messages_email_send_status`
**Credit usage:** `0 credits` — [Learn more about API pricing and credits](https://docs.apollo.io/docs/api-pricing).
Use the Check Email Send Status endpoint to check the current delivery status of an email message.
This is typically used after calling the Send
Email Now endpoint, since emails are sent asynchronously and a successful send response only
means the email was queued.
You must provide the `id` of the email message. The message
must belong to your team, otherwise a `404` is returned.
The response always includes the
message `id`, its current `status`, and a human-readable `message`. The remaining fields depend
on the status:- If the email was delivered (`completed`), a `completed_at` timestamp is
included.
- If the email failed (`failed`), a `not_sent_reason`, `failure_reason`, and `failed_at`
timestamp may be included.
- If the email is still being processed (like `drafted` or `scheduled`),
a `retry_after_seconds` value is included to indicate how long to wait before checking again.
