COR_OUTBOX_HEADERS
This table shows the COR_OUTBOX_HEADERS table API:
| COR_OUTBOX_HEADERS | Description | 
|---|---|
| C_ID | The row's primary key - all of the provided database schemas have this set as auto-increment. | 
| C_OUTBOX_ID | Used to join the headers to the message's COR_OUTBOX_ENTRY row. As such, this value should be the same as the message's COR_OUTBOX_ENTRY C_ID column. | 
| C_HEADER_KEY | The key used to describe the type of header. For valid keys, see "Message headers". | 
| C_HEADER_VALUE | The header's value. | 
If any of the required headers are not provided, then a Confirm BOD for that message is created by ION Service.
For the headers to be used, see Message headers.
In case a document is sent with deflate compression, a new parameter must be provided by the application to the Outbox headers table:
- C_HEADER_KEY = "Compression"
 - C_HEADER_VALUE = "DEFLATE"
 
When such parameter or header is received by ION, then the incoming message is considered as deflated.
