Body Structure

{
    "fmServer": "<IpAddress>",
    "method": "<methodName>",
    "methodBody": {<method specific body>},
    "session": {
        "token": "<sessionToken>",
        "required": <true/false>
    }
}

Method Examples

1. Signin 

Used for signing into the FileMaker database.

{
    "fmServer": "<IpAddress>",
    "method": "signin",
    "methodBody": {
       
        "database": "<Filemaker_Filename>"
    },
    "session": {
        "token": "",
        "required": ""
    }
}

2. Signout 

Used for signing out from the FileMaker server.

The session.token should be the token received from the Signin method.

{
    "fmServer": "<IpAddress>",
    "method": "signout",
    "methodBody": {
        "database": "<Filemaker_Filename>"
    },
    "session": {
        "token": "<sessionToken>",  // Token received from the Signin method
        "required": <true/false>
    }
}

3. Get All Records 

Fetches all records from the specified layout, with pagination.

The session.token should be the token received from the Signin method.

Pagination Options (Optional):
  • offset: The starting point of records to fetch. If offset is provided (e.g., 1), it will start fetching from the second record (indexing starts from 0).  Default: 0 (starts from the first record).
  • limit: The maximum number of records to fetch. If limit is provided (e.g., 10), it will fetch up to 10 records per request.  Default: No limit (all records will be fetched).

These fields are optional and can be omitted if you want to fetch all records without pagination.

Example:

  • If offset is 1 and limit is 10, it will fetch records from index 1 to 10 (inclusive).
  • If neither offset nor limit is specified, it will fetch all available records.
{
    "fmServer": "<IpAddress>",
    "method": "getAllRecords",
    "methodBody": {
        "database": "<Filemaker_Filename>",
        "layout": "<Layout_Name>",
        "offset": "1",  // Optional - Starting from the second record
        "limit": 10     // Optional - Fetch up to 10 records
    },
    "session": {
        "token": "<sessionToken>",  // Token received from the Signin method
        "required": <true/false>
    }
}

4. Create Record 

Used for creating a new product record in a specified FileMaker layout.

The session.token should be the token received from the Signin method.

Product Record Fields:

The fields in the record object should match the product-related field names in the FileMaker layout. Example fields might include ProductName, ProductCode, Price, Quantity, etc.

Example:

{
    "fmServer": "<IpAddress>",
    "method": "createRecord",
    "methodBody": {
        "database": "<Filemaker_Filename>",
        "layout": "<Layout_Name>",  // The layout that holds the product records
        "record": {
            "ProductName": "Laptop",     // Example product name
            "ProductCode": "LP123",      // Example product code
            "Price": "1200",             // Example product price
            "Quantity": "50"             // Example quantity in stock
        }
    },
    "session": {
        "token": "<sessionToken>",  // Token received from the Signin method
        "required": <true/false>
    }
}

5. Delete Record 

Used for deleting a record from a specified FileMaker layout.

The session.token should be the token received from the Signin method.

Record Deletion:

You need to specify the recordId of the record you want to delete. The recordId refers to the unique identifier for the record in the FileMaker layout.

Example:

{
    "fmServer": "<IpAddress>",
    "method": "deleteRecord",
    "methodBody": {
        "database": "<Filemaker_Filename>",
        "layout": "<Layout_Name>",  // The layout from which the record will be deleted
        "recordId": "<Record_ID>"   // The unique ID of the record to delete
    },
    "session": {
        "token": "<sessionToken>",  // Token received from the Signin method
        "required": <true/false>
    }
}

6. Update Record 

Used for updating an existing record in a specified FileMaker layout.

The session.token should be the token received from the Signin method.

Record Update:

You need to specify the recordId of the record you want to update. The fields in the record object should match the field names in the FileMaker layout, and they should be updated with the new values.

Example:

{
    "fmServer": "<IpAddress>",
    "method": "updateRecord",
    "methodBody": {
        "database": "<Filemaker_Filename>",
        "layout": "<Layout_Name>",  // The layout in which the record will be updated
        "recordId": "<Record_ID>",  // The unique ID of the record to update
        "record": {
            "ProductName": "Updated Laptop",   // Updated product name
            "ProductCode": "LP1234",           // Updated product code
            "Price": "1300",                   // Updated price
            "Quantity": "40"                   // Updated quantity
        }
    },
    "session": {
        "token": "<sessionToken>",  // Token received from the Signin method
        "required": <true/false>
    }
}

7. Find Record 

Used for finding specific records in a specified FileMaker layout.

The session.token should be the token received from the Signin method.

Search Criteria:

You can specify search criteria in the query field. Each query defines the fields you want to search for and the values to match. You can also apply sorting and specify scripts to run.

Query Options:
  • query: Define search criteria. Each object inside the query array represents a field-value pair that you want to search for.
  • sort: (Optional) Specify sorting order based on a field, e.g., CreationTimestamp.
  • scripts: (Optional) Specify FileMaker scripts to be executed during the search.
  • limit: (Optional) Limit the number of records returned.
  • offset: (Optional) Define the starting point for pagination.

Example:

{
    "fmServer": "<IpAddress>",
    "method": "findRecord",
    "methodBody": {
        "database": "<Filemaker_Filename>",
        "layout": "<Layout_Name>", 
        "offset": "1",              // Optional
        "limit": "10",              // Optional
        "query": [
            {"ProductName": "=Laptop"},   // Search for records where ProductName equals "Laptop"
            {"Price": ">1000"}            // Search for records where Price is greater than 1000
        ],
        "sort": [
            {"fieldName": "CreationTimestamp", "sortOrder": "ascend"} 
        ],
        "scripts": {
            "script": "<FM_Script_Name>",              
            "script.param": "<Script_Param>"           
        }
    },
    "session": {
        "token": "<sessionToken>",  // Token received from the Signin method
        "required": <true/false>
    }
}

8. Upload Container

Used for uploading a container field (e.g., an image or file) to a specified record in a FileMaker layout.

The session.token should be the token received from the Signin method.

Required Parameters for Upload:
  • database: The name of the FileMaker database where the container field resides.
  • layout: The layout that contains the record with the container field.
  • recordId: The unique ID of the record that will hold the uploaded file.
  • fieldName: The name of the container field in which the file will be stored.
  • file: The actual file to upload (this is typically included as a part of the request body, but the example provided does not show the file).
Example for Uploading a File Using multipart/form-data with Generic Data:
curl --location 'http://<Api Server>/api/dataApi' \
--header 'Authorization: Basic <Base64(username:password)>' \
--form 'method="uploadContainer"' \
--form 'data={
    "fmServer": "<IpAddress>",
    "database": "DatabaseName",
    "layout": "LayoutName",
    "recordId": "1",
    "fieldName": "ContainerFieldName",
    "sessionToken": "Session-token"
}' \
--form 'file=@"/path/to/your/file.jpg"'  # path to the file you want to upload
