Events

Get events by creation number

get

Event types are globally identifiable by an account address and monotonically increasing creation_number, one per event type emitted to the given account. This API returns events corresponding to that that event type.

Path parameters
addressstring · hexRequired

A hex encoded 32 byte Aptos account address.

This is represented in a string as a 64 character hex string, sometimes shortened by stripping leading 0s, and adding a 0x.

For example, address 0x0000000000000000000000000000000000000000000000000000000000000001 is represented as 0x1.

Example: 0x88fbd33f54e1126269769780feb24480428179f552e2313fbe571b72e62a1ca1
creation_numberstring · uint64Required

A string containing a 64-bit unsigned integer.

We represent u64 values as a string to ensure compatibility with languages such as JavaScript that do not parse u64s in JSON natively.

Example: 32425224034
Query parameters
startstring · uint64Optional

A string containing a 64-bit unsigned integer.

We represent u64 values as a string to ensure compatibility with languages such as JavaScript that do not parse u64s in JSON natively.

Example: 32425224034
limitinteger · uint16Optional

Max number of events to retrieve.

If unspecified, defaults to default page size

Get events by event handle

get

This API uses the given account address, eventHandle, and fieldName to build a key that can globally identify an event types. It then uses this key to return events emitted to the given account matching that event type.

Path parameters
addressstring · hexRequired

A hex encoded 32 byte Aptos account address.

This is represented in a string as a 64 character hex string, sometimes shortened by stripping leading 0s, and adding a 0x.

For example, address 0x0000000000000000000000000000000000000000000000000000000000000001 is represented as 0x1.

Example: 0x88fbd33f54e1126269769780feb24480428179f552e2313fbe571b72e62a1ca1
event_handlestringRequired

String representation of a MoveStructTag (on-chain Move struct type). This exists so you can specify MoveStructTags as path / query parameters, e.g. for get_events_by_event_handle.

It is a combination of:

  1. move_module_address, module_name and struct_name, all joined by ::
  2. struct generic type parameters joined by ,

Examples:

  • 0x1::coin::CoinStore<0x1::aptos_coin::AptosCoin>
  • 0x1::account::Account

Note:

  1. Empty chars should be ignored when comparing 2 struct tag ids.
  2. When used in an URL path, should be encoded by url-encoding (AKA percent-encoding).

See doc for more details.

Example: 0x1::coin::CoinStore<0x1::aptos_coin::AptosCoin>Pattern: ^0x[0-9a-zA-Z:_<>]+$
field_namestringRequired

Name of field to lookup event handle e.g. withdraw_events

Query parameters
startstring · uint64Optional

A string containing a 64-bit unsigned integer.

We represent u64 values as a string to ensure compatibility with languages such as JavaScript that do not parse u64s in JSON natively.

Example: 32425224034
limitinteger · uint16Optional
