Events

Get events by creation number

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.

GEThttps://apt.nownodes.io/v1/accounts/{address}/events/{creation_number}

Path parameters

address*Address (string (hex))

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_number*U64 (string (uint64))

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

Body

application/json

version*U64 (string (uint64))

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"

guid*EventGuid (object)

sequence_number*U64 (string (uint64))

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"

type*MoveType (string)

String representation of an on-chain Move type tag that is exposed in transaction payload. Values: - bool - u8 - u16 - u32 - u64 - u128 - u256 - address - signer - vector: vector<{non-reference MoveTypeId}> - struct: {address}::{module_name}::{struct_name}::<{generic types}>

Vector type value examples:
  - `vector<u8>`
  - `vector<vector<u64>>`
  - `vector<0x1::coin::CoinStore<0x1::aptos_coin::AptosCoin>>`

Struct type value 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).

Pattern: ^(bool|u8|u64|u128|address|signer|vector<.+>|0x[0-9a-zA-Z:_<, >]+)$

Get events by event handle

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.

GEThttps://apt.nownodes.io/v1/accounts/{address}/events/{event_handle}/{field_name}

Path parameters

address*Address (string (hex))

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_handle*MoveStructTag (string)

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_name*IdentifierWrapper (string)

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