Search Leads by Criteria
This downloads our complete API collection, including all endpoints—not just this specific endpoint.
Returns leads based on criteria you define. For example, you can search for all leads that are created after a certain date or all leads where age > 22.
Note:
- If Object Types are enabled on your account, the field (
LeadType) value is set to OT_0 by default. - You can change the
LeadTypefrom the default value (OT_0) to a custom value (OT_1, OT_2, and so on) only once. After you change it, you cannot update it again.

Request Parameters
| Parameter | Description |
|---|---|
| LookupName | Schema name of the lead field. For example, if you want to find all leads based on last name, then pass “LookupName”: “LastName”. To get the schema names for all lead fields use the LeadsMetaData API. |

| SqlOperator | Operator: One of =, LIKE, >, <, <=, >=, <> For an exact match pass “SqlOperator”:”=” |
| Include_CSV | Lead fields that should be included in the result. Use the schema names of lead fields. |
| ColumnName | The column on which results will be sorted. For example, if you want results to be shown based on creation date, pass “CreatedOn”. |
| Direction | Direction “1” means descending order and “0” means ascending order. |
| PageIndex | The results matching your criteria may be large. You can fetch the result in blocks of “PageSize” and make multiple calls to the API with increasing values of “PageIndex”. For example, you can specify “PageIndex”: 1, “PageSize”: 100 for the first call and specify “PageIndex”: 2, “PageSize”: 100 for second call. |
| PageSize | The results matching your criteria may be large. You can fetch the result in blocks of “PageSize” and make multiple calls to the API with increasing values of “PageIndex”.

| LeadType | If Object Types are enabled on your account, the LeadType value is OT_0 by default, and you can change it to a custom value (OT_1, OT_2, and so on) only once, after which you cannot update it again. This is optional. |
