Advanced HTTPS API
https
Type: object
This option represents the options used to make HTTPS requests.
alpnProtocols
Type: string[]
Default: ['http/1.1']
Acceptable ALPN protocols.
If the http2 option is true, this defaults to ['h2', 'http/1.1'].
rejectUnauthorized
Type: boolean
Default: true
If true, it will throw on invalid certificates, such as expired or self-signed ones.
checkServerIdentity
Type: (hostname: string, certificate: DetailedPeerCertificate) => Error | undefined
Default: tls.checkServerIdentity
Custom check of the certificate. Useful for pinning certificates.
The function must return undefined if the check succeeded.
If it failed, an Error should be returned.
Note:
- In order to have the function called, the certificate must not be expired, self-signed nor with an untrusted-root.
Check Node.js docs for an example.
serverName
Type: string
Default: undefined
Server name for the Server Name Indication (SNI) TLS extension.
This is useful when requesting to servers that don't have a proper domain name but use a certificate with a known CN/SAN.
import got from 'got';
// Request to IP address with specific servername for TLS
await got('https://192.168.1.100', {
https: {
serverName: 'example.com'
}
});
certificateAuthority
Type: string | Uint8Array | string[] | Uint8Array[]
Note:
- The option has been renamed from the
caTLS option for better readability.
Overrides trusted CA certificates.
Defaults to CAs provided by Mozilla.
import got from 'got';
// Single Certificate Authority
await got('https://example.com', {
https: {
certificateAuthority: fs.readFileSync('./my_ca.pem')
}
});
key
Type: string | Uint8Array | string[] | Uint8Array[] | object[]
Private keys in PEM format.
Multiple keys with different passphrases can be provided as an array of {pem: <string | Uint8Array>, passphrase: <string>}.
Note:
- Encrypted keys will be decrypted with
https.passphrase.
passphrase
Type: string
Shared passphrase used for a single private key and/or a PFX.
certificate
Type: string | Uint8Array | string[] | Uint8Array[]
Note:
- The option has been renamed from the
certTLS option for better readability.
Certificate chains in PEM format.
One certificate chain should be provided per private key.
When providing multiple certificate chains, they do not have to be in the same order as their private keys in https.key.
pfx
Type: string | Uint8Array | string[] | Uint8Array[] | object[]
PFX or PKCS12 encoded private key and certificate chain. Using https.pfx is an alternative to providing https.key and https.certificate individually. A PFX is usually encrypted, then https.passphrase will be used to decrypt it.
Multiple PFX can be provided as an array of unencrypted buffers or an array of objects like:
{
buffer: string | Uint8Array,
passphrase?: string
}
certificateRevocationLists
Type: string | Uint8Array | string[] | Uint8Array[]
Note:
- The option has been renamed from the
crlTLS option for better readability.
secureOptions
Type: number
Optionally affect the OpenSSL protocol behavior, which is not usually necessary. This should be used carefully if at all!
The value is a numeric bitmask of the SSL_OP_* options from OpenSSL.
For example, to allow connections to legacy servers that do not support secure renegotiation, you can use crypto.constants.SSL_OP_LEGACY_SERVER_CONNECT.
import crypto from 'node:crypto';
import got from 'got';
// Allow connections to servers with legacy renegotiation
await got('https://legacy-server.com', {
https: {
secureOptions: crypto.constants.SSL_OP_LEGACY_SERVER_CONNECT
}
});

Examples
import got from 'got';
// Single key with certificate
await got('https://example.com', {
https: {
key: fs.readFileSync('./client_key.pem'),
certificate: fs.readFileSync('./client_cert.pem')
}
});
// Multiple keys with certificates (out of order)
await got('https://example.com', {
https: {
key: [
fs.readFileSync('./client_key1.pem'),
fs.readFileSync('./client_key2.pem')
],
certificate: [
fs.readFileSync('./client_cert2.pem'),
fs.readFileSync('./client_cert1.pem')
]
}
});
// Single key with passphrase
await got('https://example.com', {
https: {
key: fs.readFileSync('./client_key.pem'),
certificate: fs.readFileSync('./client_cert.pem'),
passphrase: 'client_key_passphrase'
}
});
// Multiple keys with different passphrases
await got('https://example.com', {
https: {
key: [
{pem: fs.readFileSync('./client_key1.pem'), passphrase: 'passphrase1'},
{pem: fs.readFileSync('./client_key2.pem'), passphrase: 'passphrase2'},
],
certificate: [
fs.readFileSync('./client_cert1.pem'),
fs.readFileSync('./client_cert2.pem')
]
}
});
// Single encrypted PFX with passphrase
await got('https://example.com', {
https: {
pfx: fs.readFileSync('./fake.pfx'),
passphrase: 'passphrase'
}
});
// Multiple encrypted PFX's with different passphrases
await got('https://example.com', {
https: {
pfx: [
{
buffer: fs.readFileSync('./key1.pfx'),
passphrase: 'passphrase1'
},
{
buffer: fs.readFileSync('./key2.pfx'),
passphrase: 'passphrase2'
}
]
}
});
// Multiple encrypted PFX's with single passphrase
await got('https://example.com', {
https: {
passphrase: 'passphrase',
pfx: [
{
buffer: fs.readFileSync('./key1.pfx')
},
{
buffer: fs.readFileSync('./key2.pfx')
}
]
}
});
