Follow [this guide](https://mimecastsupport.zendesk.com/hc/en-us/articles/34000360548755-API-Integrations-Managing-API-2-0-for-Cloud-Gateway#h_01JK62GWQ91FX2VPS7EWE3M9RX) to generate Mimecast access and secret keys. 2. Complete the process on the Hunters platform, following [this guide](https://hunters.document360.io/docs/connect-a-data-source). ### Using S3 storage Hunters supports the ingestion of Mimecast logs via an intermediary AWS S3 bucket. **To connect Mimecast logs:** 1. Export your logs from Mimecast to an AWS S3 bucket. 2. Once the export is completed and the logs are collected to S3, follow the steps in [this section](/v1/docs/connect-data-through-aws-s3). Hunters expects the data to be divided to prefix per data type, which can be achieved by using the Content-Disposition response header in the Mimecast API. More details can be found [here](https://integrations.mimecast.com/documentation/tutorials/understanding-siem-logs/), under the “Understanding the Logs API” section. ## Expected format The supported format us , `json`. The expected schema is as it returns from the API. ### Delivery logs ```json {  "deliveryErrors": null,  "numberAttachments": "2",  "tlsUsed": "true",  "deliveryTime": "27106",  "subject": "RE: [REDACTED SUBJECT]",  "senderEnvelope": "redacted.sender@example.com",  "delivered": "true",  "rejectionType": null,  "destinationIp": "123.123.123.123",  "aggregateId": "redactedAggregateId",  "processingId": "redactedProcessingId",  "tlsCipher": "TLS_AES_256_GCM_SHA384",  "timestamp": 1757310695432,  "direction": "inbound",  "emailSize": "530901",  "tlsVersion": "TLSv1.3",  "Hostname": "redacted.hostname.com",  "messageId": "",  "eventType": "delivery",  "deliveryAttempts": "1",  "accountId": "redactedAccountId",  "route": "Mimecast Direct to Exchange Online",  "rejectionInfo": null,  "recipients": "redacted.recipient@example.com",  "rejectionCode": null,  "subType": "true",  "totalSizeAttachments": "157968" } ``` ### AV Logs ```json {  "fileName": "ANON_FILE_MT103_ANON12345.zip",  "sha256": "ANON9c4d2a1e3b7f48b8a7e16e21d0a9f6f4f8c9e3bba726b1a2a0c6d88c4a9f1b2d",  "subject": "ANON Swift Message MT103 Bank ad: ANON987654PQ",  "senderEnvelope": "anon_sender@anondomain.com",  "messageId": "",  "senderDomainInternal": "false",  "eventType": "av",  "sha1": "ANON4b6a91a2c8d7e2f4b1d3c6f91b2e7f4d7c9a8e1b",  "accountId": "ANON12345",  "aggregateId": "ANONpQ8xLmN3yVzT4rQw9kRbHg",  "virusFound": "Failed Known address verification",  "route": "inbound",  "processingId": "ANONtZ7qPjH59LmWkRn4sXyQdAeUfCv9oBr2jKpXvNwLhS8_1756970571",  "recipients": "anon_user@anonmail.org",  "fileExtension": "zip",  "subType": null,  "senderIp": "203.0.113.25",  "senderDomain": "anondomain.com",  "timestamp": 1756970583782,  "emailSize": "ANON845219",  "md5": "ANON8e5d2c7a19f4b3d8a6c2e9f7b1d4c6a2" } ``` ### Attachment protect logs ```json {  "fileName": "FILE_REDACTED.txt",  "sha256": "HASH_SHA256_REDACTED",  "subject": "Globalscape Notification: PROJECT_NAME_REDACTED -
